Hello Tim,
Thank you for your questions and I am happy to answer.
- We are not offering any discount for a single license at the moment. If you are interested in a multiple license activation please drop us a note via the plugin in Pefrormance>Support.
- Without looking at the logs I cannot share any specifics on why this may be occurring. Make sure that the Object Cache and DB cache are not enabled, especially if caching to disk and on the shared server. If those options are enabled, disable them, save all settings and purge the cache and see if the issue persists.
If the DB is the bottleneck of your website performance, I would recommend upgrading the hosting plan and usin memory-based caching for DB like Redis or Memcached.
Thanks!
Hello Kevin,
Thank you for your inquiry and I am happy to assist you with this.
Thank you for your support and as I can see in the test, the results are amazing. This chain response time is not incrementing, so it’s not 2.5 s but 650ms as you can see in the waterfall chart.
So there is nothing to worry about in this case as the time to interactive is 0.4 s
Thanks!
Hello Mark,
As you already stated those are external files and no plugins can handle those files because they are coming from an external server.
If Minify is set to Auto you may try to Include external files/libraries: option in Performance>Minify>Advanced and enable the option “Use Regular Expressions for file name matching”
The best solution is to host those files on your server.
Thanks!

Hello,
I am sorry about the issue you are experiencing and I am happy to assist you with this.
Can you please make sure that all files are completely removed before reinstalling the plugin?
1. Purge Cache 2. Deactivate and Delete Plugin 3. Check .htaccess File (make backup) W3TC will create many directives in .htaccess file to control the caching behavior. Each section will start and end with comments like "#BEGIN W3TC Page Cache core" and "#END W3TC Page Cache core". Ensure that no residual entries are left over in your .htaccess file after deleting the plugin. 4. Delete wp-content files and folders - cache folder - w3tc-config folder - object-cache.php (if exists) - advanced-cache.php (if exists) - dbcache.php (if exists) - upgrade folder - delete w3-total-cache folder in wp-content (if exists) 5. Delete Cached Files from CDN (if using CDN) Besides deleting all the relevant files, if you use CDN then ensure to purge the cached content from your CDN. This is necessary when you enabled minify option in W3TC settings. You should delete the minified and combined scripts and CSS files from your CDN server to avoid the site breaking on the browser. 6. Go to your wp dashboard and re-install W3 Total Cache Thanks!
Hello Bart,
I am sorry about the issue you are experiencing and I am happy to assist you with this.
Without looking into the logs there is no way we can be 100% sure what might be causing this. Most likely is a memory issue on the server. So make sure that you are not using Database Cache and Object Cache if on a shared server and caching to disk. Also, check the size of wp-content/cache/ folder
There is also a possibility of a conflict with some other plugin so you may want to check that by disabling other plugins while W3TC is enabled.
Thanks!
Hello Eugene,
MaxCDN is now Stackpath and it’s not ours, it’s something we recommend as a CDN provider. It is not recommended to use more than one CDN solution. Simply to avoid any issues. however, since these are two different types of CDN, you can try serving the static assets from the CDN by using Stackpath.
Please check this article for more details.
Thanks!
Hello Chris,
I’ve replied to the email. Please continue correspondence there and follow the instructions so we can avoid sharing any private info on a public forum.
Thanks!
Hello Chris,
I can see that the license is activated on your website.
Remove the license key from Performance>General settings, Licensing sub-box, license field, and save all settings. Re-enter the license, verify the license with the “verify license button” and save all settings.
W3 Total Cache Pro should be active after these steps!
Thanks!
Hello Mike,
There is an example config wp-content/plugins/w3-total-cache/ini/dbcluster-config-sample.php
Once edited create /wp-content/db-cluster-config.php and paste the config there. It should work after these steps.
Thanks!
Hello Eugene.
Thank you for your inquiry and I am happy to assist you with this.
As I can see, the WPX CDN needs to be enabled in the WPX Control Panel. AS this is being done outside of W3TC there is no need to do anything in W3 Total Cache.
Thanks!
Hello Mike,
With W3TC PRO you may use a cluster of MySQL servers when a single MySQL instance can’t handle all your traffic.Thanks!
Hello Ketil,
W3 Total Cache Pro licenses are valid on a per-install basis, meaning you need one for every WordPress instance you run. If you have three separate websites, you will need three licenses in total—one for each site. If you have five sites in a WordPress multisite instance, you need just one license for all five sites.
Thanks!Hello,
I am sorry about the issue you are experiencing with the images and I am happy to assist you with this.
Can you please disable the settings one by one in Performance>general settings, save the settings and purge the cache after each setting is disabled and see which one might be causing the issue?
Thanks!
Hello Mike,
Using more than one plugin for this is not recommended.
If you are planning to use the mentioned plugin you should disable W3TC db caching as both plugins are using the same drop-in – db.php.Thanks!
Hello Kiem,
Please make sure to check this link for assistance with this and also check the Performance>Install page for more details.

Thanks!Hello Aninda,
Thank you for your inquiry and I am happy to assist you with this.
Are you trying to setup FSD CDN or just serving the static assets from the AWS?
Can you please share the screenshot of the settings in Performance>CDN>Configuration: Objects?
Thanks!Hello Kiem,
I am sorry about the issue you are experiencing and I am happy to assist you with this.
Can you please share the screenshot or more detailed information about where you are seeing the error message?
A screenshot would be great.
Thanks!Hello Michael,
I am sorry about the issue you are experiencing with mixed content and I am happy to assist you with this.
I would recommend completely removing and re-installing W3 Total Cache, including all residual files:
1. Purge Cache
2. Deactivate and Delete Plugin
3. Check .htaccess File (make a backup)
W3TC will create many directives in the .htaccess file to control the caching behavior. Each section will start and end with comments like “#BEGIN W3TC Page Cache core” and “#END W3TC Page Cache core”.
Ensure that no residual entries are leftover in your .htaccess file after deleting the plugin.
4. Delete wp-content files and folders
– cache folder
– w3tc-config folder
– object-cache.php (if exists)
– advanced-cache.php (if exists)
– dbcache.php (if exists)
– upgrade folder
– delete w3-total-cache folder in wp-content (if exists)
5. Delete Cached Files from CDN (if using CDN)
Besides deleting all the relevant files, if you use CDN then ensure to purge the cached content from your CDN. This is necessary when you enabled minify option in W3TC settings. You should delete the minified and combined scripts and CSS files from your CDN server to avoid the site breaking on the browser.
6. Go to your wp dashboard and re-install W3 Total CacheOnce enabled, Enable the settings one by one, save all settings and purge the cache after each setting is enabled, and make sure to check your website.
Also in Page Cache, make sure that the option “Cache SSL (HTTPS) requests” is enabled
I hope this helps!Hello Mitchell,
Thank you for the information.
I’ve checked your website and as I can see the website is accessible as well as the https://custom-tiles.com/wp-admin/ and W3 Total Cache is active on your website.<!-- Performance optimized by W3 Total Cache. Learn more: https://www.boldgrid.com/w3-total-cache/ Page Caching using disk: enhanced Content Delivery Network via N/A Lazy Loading Minified using disk Served from: custom-tiles.com @ 2021-02-24 19:55:39 by W3 Total Cache -->Can you please confirm that you are still experiencing the issue?
Thanks!Hello Mitchell,
The provided steps need to be taken first in order to access your dashboard. So to access your dashboard you need to manually delete those files from the server following the steps provided.
Once those files are deleted, you can then access the dashboard and re-install W3TC and making sure that OC and DB Cache are not enabled.
What hosting support did is most probably disabled the plugin by renaming it in the wp-content/plugins/
The problem is that the settings you enabled are still in wp-content/w3tc-config/master.php and the cached files are in the /cache/ folder.
Thanks!Hello Mitchell,
Simple deactivation of the plugin is not sufficient.
Please follow the steps provided and completely remove everything related to W3 Total Cache.
Once that’s done, install W3 Total Cache without any leftover files remaining and make sure not to use Object Caching and Database caching if on shared hosting and if caching to Disk.
Thanks!Hello Mitchell,
I am sorry about the issue you are experiencing and I am happy to assist you with this.
Can you please completely remove W3 Total Cache and re-install it and once the plugin is reinstalled make sure that Object Cache and Database Cache are not enabled in the General settings especially if on shared hosting and if caching to disk and see if the issue persists:
1. Check .htaccess File (make a backup)
W3TC will create many directives in the .htaccess file to control the caching behavior. Each section will start and end with comments like “#BEGIN W3TC Page Cache core” and “#END W3TC Page Cache core”.

2. Delete wp-content files and folders
– cache folder
– w3tc-config folder
– object-cache.php (if exists)
– advanced-cache.php (if exists)
– dbcache.php (if exists)
– upgrade folder
– delete w3-total-cache folder in wp-content/plugins/ (if exists)
3. Delete Cached Files from CDN (if using CDN)
Besides deleting all the relevant files, if you use CDN then ensure to purge the cached content from your CDN. This is necessary when you enabled minify option in W3TC settings. You should delete the minified and combined scripts and CSS files from your CDN server to avoid the site breaking on the browser.

Thanks!Hello Hannah,
Thank you for your inquiry and I m happy to assist you with this.
In order to be able to use the Opcode caching method (APC/APCu for example ), you need to make sure that the PHP extension is installed on your server. Only then you will be able to choose it from the Page Cache Method: list.
However, I would advise keeping the Page Cache Method: on Disk: Enhanced as it providing the best results when it comes to Page Caching.
Thanks!Hallo Maarten,
Thank you for your inquiry and I am happy to assist you with this.
As you can see in the gtmetrix report The total size of your website is 10.7MB and 9.04MB or that are images. Gtmetrix suggests that you need to optimize images, which W3 Total Cache cannot do. So the bottleneck of your website performance is your images.
Gtmertix also suggests using CDN to serve static content and I would suggest Stackpath CDN as it’s easy to set up and it offers the best performance.
As for eliminating render-blocking css, W3 Total Cache does have an option “eliminate render-blocking CSS by moving it to HTTP body” however that option is available after updating to Pro.
Thanks!Hello Steven,
Thank you for your inquiry and I am happy to assist you with this.
The notification you are seeing suggests that the CDN is not enabled in Performance>General settings:
So make sure that the CDN option is enabled and Stackath is selected under the CDN type, save all settings, and purge the cache.
Also, make sure to check this article about how to setup Stackpath with W3 Total Cache.
Thanks!Hello Tony,
Thank you for the information and I am sorry that the issue is still occurring.
Please check this article about the wp debug and error logs. From what you’re saying the uploads times out for some reason so you should check if there are any errors in the log, wp-debug or any PHP errors.
Thanks!Hello Emmanuel,
As I’ve already replied via the support channel, to access the premium support for W3 Total Cache, please navigate to your wp dashboard, Performance>Support, and purchase the Performance Audit solution.
After that, we will provide you further instructions in the Premium support email chain.
Thanks!
Hello Tony,
Thank you for the info.
Can you please check your error log?
If the error.log is not showing anything there is a possibility that the upload timed-out and it takes too much time for your host to upload file and timeout are set to lower value to process responses on your host.
So, in this case, you should increase it.
There is also a possibility that Wordfence or some other security plugin or firewall could be blocking W3TC from accessing too many directories/files at once.
Thanks!Hello Joshua,
I’ve inspected your website and I can see that the calendar is not loaded (infinity loading). After checking the Console errors I saw a 404 error for https://headshotsla.com/?wc-ajax=wc_bookings_find_booked_day_blocks&product_id=1046777&wc-ajax=wc_bookings_find_booked_day_blocks&security=15c6cabcbb&min_date=2021-02-15&max_date=2021-03-22
This is for page https://headshotsla.com/product/8-look-8-retouch/
Can you please disable the W3TC settings one by one in Performance>General settings, save all settings and purge the cache after each setting is disabled, and see which setting might be causing this.
Thanks!Hello Tony,
Thank you for the information and I am glad you managed to set up the CDN successfully.
Check if you have the information about the Unsuccessful transfer queue, click the button near it and try to re-upload files.
if works – it’s a temporary issue linked to server resources.
Also, make sure to check your master.php file. If cdn.force.rewrite”: “1 should be avoided in the long-term since it causes continuous reuploads of the same files. Just change it to cdn. force.rewrite”: “0
Thanks!Hello Matteo,
Thank you for the information.
In the July 2020 update, we’ve fixed the following:- Fixed Take “Accepted Query Strings” into account when “Cache query strings” enabled
- Fixed the typo in the variable for lazy loading
- Added lazy load Google Maps reference to the general settings page
- Added Support background-image: together with background: for lazy loading
So there is nothing that would suggest the issue you are referring to except if you are possibly caching a query string.
As I can see you are using Page Cache with Memcached. I would suggest switching to Disk: Enhanced, as it’s more performant than any other caching method when it comes to page caching, and see if the issue persists.
Thanks!Hello Tony,
The settings are saved in wp-content/w3tc-config/master.php Make sure to make a backup of the mentioned file.
YOu can manually replace the lines around line 572 (depending on the configuration) with default values:"cdn.azure.user": "", "cdn.azure.key": "", "cdn.azure.container": "", "cdn.azure.cname": [], "cdn.azure.ssl": "auto",Once you save the changes, go to Performance Dashboard and re-enable CDN (make sure CDN is disabled before this), and select Microsoft Azure Storage from the CDN type menu.
Once you go to Performance>CDN the values should be default.
Thanks!Hello Matteo
The most likely issue is that there are leftover files of the other caching plugin you are using and therefore is making a conflict with W3 Total Cache.
We cannot assist you in this case unless you completely remove the other plugins and make sure there are no leftover files.
Alternatively, we can offer you our premium support in Performance>Support.
Thanks!Hello Mattei,
It would be great if you could share your website URL.
The Cron schedule for W3TC is not correct. I am not able to see the screenshot at the moment.
There is a possibility of a conflict so you should make sure that you do not have any other caching solution installed like server-side caching or any other caching plugin and make sure to disable it.
Thanks!Hello Tony,
I am sorry about the issue you are experiencing with setting up Azure CDN with W3 Total Cache and I am happy to assist you with this.
The replace hostname should be automatically populated after connecting with the Account key as you can see in the image below:
I would recommend checking out this article which explains the proper setup of Azure CDN with W3 Total Cache.
Please let me know if you have any other questions.
Thanks!Hello Joshua,
Thank you for your inquiry and I am happy to assist you with this.
As I can see from the tests you have a lot of render-blocking CSS. This means that you should eliminate render-blocking CSS and that feature is available in W3 Total Cache after upgrading to Pro.
So yes in this case you need the Pro version for the plugin. As for our premium support, you can purchase Plugin Configuration or Performance Audit solution via the plugin in Performance>Support.
Thanks!Hello Matteo,
I am sorry about the issue you are experiencing with corn schedules and I am happy to assist you with this.
As you can see W3TC does have a few events scheduled, depending on features enabled in the General settings.
Also, as I can see in the screenshot WP_CRON_LOCK_TIMEOUT constant is defined to 60sWhen WordPress is loaded, it checks to see if a cron job is running (if cron is locked). If cron is not locked, it will try to create a lock – if the lock timeout has not been reached, no lock can be acquired and cron will not run.
The constant is limiting the W3TC schedules and therefore those are not executed. You should either change the limit or comment out the WP_CRON_LOCK_TIMEOUT line in wp-config.
I hope this helps!
Thanks!
