Hello,
Thank you for reaching out and I am happy to assist you with this.
The W3 Total Cache has the option for Gzip and you can find this option in Performance>Browser Cache, in the General box for all types of files or you can enable/disable it for individual files type.
If the Gzip compression is disabled, then the W3 Total cache does not compress any files.
You can check this by checking the .htaccess file for any mod_deflate-related W3TC rule.
Can you please share your settings and also share the URL so I can see if the files are indeed gzipped?
Thanks!Hello Hasmik,

Hello,
Thank you for your feedback. I forgot to mention that the in-depth Audit of your website is Premium support. This is because this includes the Audit of all the plugins, servers, and impact of the 3rd party resources, and for that we need access.
So the optimization of your website may be out of any plugin’s hands and possibilities.
I hope this clarifies my reply.Hello Duane,

Hello Saif,
Thank you for your feedback.
I’ve removed the license key as this is a public forum, and as I can see the license key is not yet applied to your installation.
The configuration depends on a lot of things. The optimal W3 Total Cache configuration takes into account a number of factors: your theme, your plugins, and the technologies available on the server. Since everyone’s site and traffic and theme are different, there is no one size fits all solution.
We are going to perform tests on your website, and provide you with some tips and guidance on what you need to do or change in order to achieve the best performance for your website.
The Caching method selected for the Page Cache minify and DB Cache are good and recommended in most cases. For Object Caching and Database Cache, it’s not recommended to use Disk-based caching so I would advise either using memory-based caching like Memcached or Redis, or not using it at all.Object Cache allows getting data from the database more efficiently. Its purpose is similar to what Database Cache does. But compared to Database Cache, Object cache is more efficient as it allows the process of fewer requests.
As a rule of thumb, Object Cache is not worth using on shared hosting for the same reason as Database Cache, i.e. database is often not the performance bottleneck, but disk input-output operations.
However, like Database Cache, it can be beneficial to use if you are on VPS or a dedicated server, get a lot of traffic, and have a lot of comments. Also, if you know that database is the bottleneck of your website performance, then Object Cache (like Database Cache) is beneficial to use. But in this case, it’s recommended to use Opcode, Memcached, or Redis options as mentioned previously.FSD CDN is great but sometimes not necessary. It depends on how good is your server and whether you are serving the website for local or worldwide users.
Thanks!
Hello,
Thank you for reaching out.
Can you please state your question in English language and let us know if this is related to the W3 Total Cache plugin or your website hosting?Thanks!
Hello Bill,
Thank you for reaching out and I am happy to assist you with this.
This is related to the W3 Total Cache, however, it’s also related to your server resources need for the W3 Total Cache to do its job.
The Error means that the PHP memory is exhausted and reached the limit of 40MB in your case, and what you need to do is to increase the memory limit.
Its recommended using 128MB or 256 MB
You can find out more on how to achieve this in this article, and if you are unsure about this, please make sure to reach out to your hosting provider.Let me know if this helps and if you have any other questions.
Thanks!
Hello Jorge,
I’ve resent all the information via the W3 Total Cache support channel and there you will receive the license key and the information on how to activate W3 Total Cache Pro.
Let me know if you received the necessary information.
Thanks!
Hello Ani,
Thank you for reaching out and I am happy to assist you with this.
There is no difference between the Free and Pro versions of the W3 Total Cache when it comes to setting expires header or cache control header.
To do this, you need to enable Browser Cache in the Performance>General settings and save all settings Then go to Performance>Browser Cache and you can enable “Set Expires header” and “Cache-control header” in the General area or for individual files like HTML&XML, JS&CSS and Media&Other files
Let me know if this helps and if you have any other questions.
Thanks!Hello Peter,
Thank you for reaching out.
On the support end, it’s better to have the topic opened for this so we can possibly check the website and have more details about the environment.
The comment section is not the best place to provide support.
Auto-convert will work once enabled in the Images service settings. You can check this by uploading a few new images. In the Media Library, you will see if the images were reconverted.
It seems that there was some connectivity problem between your server and the W3TC API at some point, or the conversion server was overloaded with the number of requests.
If convenient, can you share the URL of the website?
Thanks!Hello John,

W3 Total Cache Pro unlocks the additional features in W3 Total Cache settings, which can improve the speed and performance of the website, depending on what the website needs in terms of improving the performance.
One thing that I can suggest is to purchase our premium support option in Performance>Support – Performance Audit.
The optimal W3 Total Cache configuration takes into account a number of factors: your theme, your plugins, and the technologies available on the server. Since everyone’s site and traffic and theme is different, there is no one size fits all solution.
This service also takes into account the idiosyncrasies of Web Performance Optimization (WPO) in a WordPress context. This means that WPO best practices have to be modified for WordPress because of how the application operates. The number of counter-intuitive realities could fill a small book.This means that the best configuration for your site might not involve enabling minify, database caching, and other things that you might expect. As a matter of fact, it can actually hurt performance by implementing features for the wrong situation.
The deliverable with this service is a faster site. It’s impossible to predict the extent to which our work will improve performance (especially true for code we didn’t write running on servers we didn’t build), but our promise is that we’ll do our best.
Additionally, we’ll send along a performance report that outlines the improvements, recommendations (if any), and what else we can do to help you reach and exceed your performance goals. There are many ways that we can help improve performance, you should think of W3 Total Cache configuration as the starting point for optimizing your site.
Upgrading to W3 Total Cache Pro makes this work even more effective, as we’ll have additional features to utilize in delivering the best possible results. It’s best to upgrade before placing your order since we can do this for you, and you can upgrade right in the Dashboard on any W3 Total Cache page.
Thanks!

Hello,
Thank you for reaching out and I am happy to assist you with this.
Can you please share more information on how W3 Total Cache settings do not affect your website and what settings are enabled In the General settings?
As I can see you have a lot of customers (or some other plugin) CSP headers and I can see that the Lazyloading is working as expected.Thanks!
Hello Louise.
Thank you for reaching out and I am happy to assist you with this.
With W3 Total Cache you can preload the cache, of course, however, it cannot be done for specific user roles.
The reason for this is that the Preload is based on the sitemap URL, which you need to add to the Cache Preload section in Peformance>Page Cache.
In any case, it’s not recommended to cache pages for logged-in users to avoid sharing any private and sensitive information which may be cached.
Once the website is preloaded with W3 Total Cache Cache Preload, those can be served for logged-in users also, however, it’s best to exclude specific pages from the cache like /account/, /checkout/, /cart/
The prices should be dynamic and firing with ajax, so those should not be cached if this is the case.Once again, it’s not recommended to cache pages for logged-in users, and I hope I explained the reason for this.
Let me know if you have any other questions.
Thanks!
Hello Jonathan,
Thank you for reaching out and I am happy to assist you with this.
W3 Total Cache supports the usage of Redis as a memory-based option. So yes Redis is naturally supported.
In order to use Redis in W3 Total Cache, and since W3TC only recognizes the PHP modules, you need to install PHP Redis module
I hope this helps and let me know if you have any other questions.Thanks!
Hello,
Thank you for reaching out and I am happy to assist you with this.
I’ve checked your website and as I can see all the Images coming from your server are converted by W3 Total Cache and served as webp, all other images coming from the external server https://ae01.alicdn.com/ are not converted since W3TC cannot handle those images as they are not on your server.
“Failed to retrieve a response. Please reload the page to try again.” this may happen on some occasions, and this depends on how many requests is the API server handling at the moment. The ajax requests you are trying every 10 sec or so and yes, this may cause the server resources to hit the limit on occasion.
Please also note that the Pro users have the advantage when it comes to image conversion, and those requests are favored by the Server.
I hope this helps!
Hello Bob,
I am sorry about any confusion with your subscription and I am happy to assist you with this.
I’ve checked the W3TC support channel and there are no emails of this kind sent from you. Can you reach out to us directly via the website contact form, and provide information about your subscription so I can check the status?
Please share the latest invoice, license key or the email used to subscribe to W3 Total Cache Pro so I can check the subscription.
I’ve removed the sensitive data from your topic because this is a public forum.Thanks!
Hello Daryl,
Thank you for reaching out and I am happy to assist you with this.
As I can see that the images are converted:
https://www.britishcolumbia.ca/wp-content/uploads/Community-Vancouver-iS471390003-TIBC-e1643405558903.webp
https://www.britishcolumbia.ca/wp-content/uploads/tibc-website-hmpagemap-830x450px-newblue.webpWhen you find that your original image has been converted to WebP, but other image sizes are missing WebP versions, you may need to double-check that your WordPress environment supports the WebP format.
While the original image is converted via our API service, the different sizes (e.g. Large, Medium, Thumbnail) are created by your own server. For this, you must have WordPress 5.8 and the appropriate libGD or ImageMagick package available on your server.
To check if your WordPress environment supports WebP, navigate to Site Health > Info > Media Handling and double-check that WebP is listed in the supported file formats for the library shown in the Active editor. If you find these are missing the WebP extension, consult your system administrator to set up the correct packages.
Please make sure to check this and let me know if you have any other questions.
Thanks!
Hello Berto,
Thank you for reaching out and I am happy to assist you with this.
You explained the process, and yes, this is correct. Once the Page Cache is purged, the cached files get the _old extension, which means that those are expired files. This is actually done to prevent loading the cached page, and force updating the page cache. The Garbage collection interval: in Performance>Page Cache>Advanced is used to remove all the _old files from the cache directory in the specific time set, which is triggered by wp_cron.
By default, the Garbage collection interval is set to one hour (3600s) and after the cache is purged, the _old files will be removed in that interval.I hope this clarifies things and answers your question.
Thanks!

Hello Piotr,
Thank you for reaching out and I am happy to assist you with this.
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. If you are interested in bulk licensing, please email us for more information.Hello Jeff,
Thank you for reaching out and I am happy to assist you with this.
The license key was sent to the email address used to subscribe to W3 Total Cache Pro. Since this is a public forum, I can not share the email or the actual license key with you here.

I’ve checked the W3 Total Cache support channel and we do have 3 emails related to your license, however, none of them is related to the license management problem.
Can you please drop us a note directly via the plugin in Performance>Support, or via the website contact form and share the link for license management
Thanks!Hello,
Sorry for the late reply I was trying to replicate the problem.
By default, minify should not be enabled for logged-in users so you should disable this option.
This is a very peculiar use case, and honestly, I’ve never had a chance to encounter this kind of issue.
As for The unsuccessful transfer queue, you should click the button near it and try to re-upload files.
if works – it’s a temporary issue linked to server resources.
You are using CDN Type: Push, and this means that invalidation of the files needs to be done manually.
The Only purge CDN manually option, if enabled is there to ensure the CDN purge is done manually due to the huge AWS bills for invalidations.
You can always submit a bug report in Performance>Support.Thanks!

The file is generated in the /app/cache/minify/ folder. In order to be served from the CDN, you may need to purge the CDN so that new files are uploaded.
If all other files are uploaded, that means that you do not need to add the path to the custom files list.Thanks!
Hello,
Thank you for reaching out and I am happy to assist you with this.
To confirm, you are also using the W3TC CDN feature to upload files to CDN, or are you using some other plugin for this?
If you are using the W3TC CDN module, can you please check if the option “Host minified CSS and JS files” is enabled in Performance>CDN>General?
Is the problem with both CSS and JS files or only CSS files are not being uploaded to the CDN?
Since the path of the files is modified (normally it should be wp-content/cache/minify/), you can try adding the path to the Custom file list: in Performance>CDN>Advanced.Thanks!
Hello,
Thank you for reaching out and I am happy to assist you with this.
W3 Total Cache check for mod_php. Not detected means you don’t use mod_php mode, so you probably use php-fpm. We cannot detect Apache modules in that case, but that doesn’t mean it is not installed/active.
We are working on improving the compatibility check in the future.Thanks!

Gzip was designed specifically to compress files. The library has been incorporated into a lot of different programs that need to compress files. The library was incorporated into web servers as compressing content started to be the norm. It was one of two compression algorithms specified in RFC 2616, the HTTPS 1.1 specification. While it wasn’t specifically designed for streaming operations like web servers, it was adapted to it.Brotli, on the other hand, was specifically designed for the web. Google recognized the need for a way to compress streams more efficiently so they designed Brotli.
If you have both settings enabled in the W3 Total Cache Browser Cache section, most of the modern browsers will favor Brotli compression and the ones that do not support it (very few) will show Gzip.I hope this answers your question.
Thanks!
Hello Diego,

Thanks!Hello Jonathan,
Thank you for reaching out.
What you want to achieve is Full site delivery via CDN. Meaning not only the static files are served from the CDN, but HTML also.
This is possible to achieve, but not the way you mentioned.
For FSD CDN, I would recommend using Stackpath CDN as a provider. Also, note that the FSD CDN feature in W3 Total Cache is only available for Pro users.
Thanks!Hello Stacey,
Thank you for reaching out and I am happy to assist you with this.
Please understand that the number of requests can be huge depending on the time of the day, and also note that W3 Total Cache Pro users have an advantage when it comes to converting images. This is why at some point conversion can take a bit longer than expected.
We are working every day to improve this process to be faster for all users.
You can safely turn the Image service off in Performance>Extensions and deactivate the feature.
Once deactivated all images will be prevented back to original state
I hope this helps!
Thanks!

Hello,

For this, you can use Page Fragment Cache as a method in W3 Total Cache to exclude specific parts of the page from being cached.
With this method, you can wrap the PHP code with(replacing the PHP tag). This will ensure that this part of the page will be excluded from Page cache.
Please note that this is only available when using Page Caching Method Disk, or Memory-based caching methods like Memcached or Redis.
You can check more about this on our FAQ page
The best method is to fire these parts with Ajax, which will automatically bypass the cache.
Thanks!
