Hello Claudio.

Well, this is a very interesting question.
The only solution for this is to exclude specific Groups from object caching in Performance>Object Cache>Non-persistent groups:
As for what needs to be excluded, I would recommend reaching out to Memberpress support as they know which groups are used in their plugin.
I hope this helps!
Thanks!

Hello Karl,

wp-.*\.php
index\.php

These are default values. W3 Total Cache does not cache pages with query strings by default so you should remove the following:

*?tve=true
*?cpo_options=1
*?et_fb=1

Make sure to save all settings and purge the cache once the lines above are removed.
Thanks!

Hello Yuri,

We have released a patch in version 2.1.8. We do apologize for any inconvenience. Please update and do let us know if there are any issues. We will be happy to assist you.
Thank you.

Hello Ed,
Thank you for the information.
You can exclude the specific image from Lazy Load in Performance>User Experience>Exclude words:
So you can try to re-enable lazy load, add the image URL to the Exclude words: area
https://www.water-line.nl/wp-content/uploads/2021/08/header-image.png
and make sure to save all settings and purge the cache.
I hope this helps!
Thanks!

Hello Yuri,

Thank you for reaching out and I am sorry about the issue you are experiencing with W3 Total Cache latest update.
This issue is reported numerous times and we already gave a Github issue reported for this.
The temporary solution is either to revert back to the previous version of W3 Total Cache or to change the permission for the robots.txt file so W3TC cannot write to it.
Thank you for your patience and I am sorry about the inconvenience.

Hello Tim,

Thank you for reaching out and I am happy to help you.
When you saying WP-Cache, are you referring to W3 Total Cache Page Caching, or setting define(‘WP_CACHE’, true); which is required for caching?
The most likely issue is that the pages are being cached once visited and therefore do not request the password.
I am not sure what you are using for the protected posts, but you should make sure to disable caching for logged-in users, and possibly exclude those posts from being cached by adding the to Performance>Page Cache>Advanced>”Never Cache following pages”.
I hope this helps!
Thanks!

Hello Voldemars,

Thank you for reaching our and I am sorry you are having issues with the W3 Total Cache.
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 Emiliano,

Thank you for the feedback.
As you can see in the stack trace:
#4 wp-content/plugins/wp-appbox/wp-appbox.php(290): w3tc_pgcache_flush_post (45407)
This means that the mentioned plugin is calling w3tc_pgcache_flush_post.
It’s called by the function in the wp-appbox.php
function wpAppbox_clearCachePlugin( $postID = '')
https://plugins.trac.wordpress.org/browser/wp-appbox/trunk/wp-appbox.php#L277
I hope this helps!
Thank you!

Hello,

Thank you for your question.
In most cases, once the plugin is deleted, all related files and folders should be deleted.
To completely remove W3TC follow the instructions below:
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)
– db.php (if exists)
– upgrade folder
– delete w3-total-cache folder in wp-content/plugins/ (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.

Thanks!

Hello Natalie,

Thank you for reaching out!
After you deactivate any plugin, you also need to delete it by clicking on the delete link just below the plugin name:

I hope this helps!
Thank you!

Hello,

Thank you for reaching out and I am happy to assist you with this.
Are you using origin push or origin pull as CDN Type?
Make sure to check out this video for more details about configuring AWS with W3 Total Cache.
Thanks!

Hello Michael,

Thank you for your question and I m happy to answer.
There is an example config ini/dbcluster-config-sample.php
once edited and placed to /wp-content/db-cluster-config.php – it starts to work
In order to use Database Cluster, you need to use WordPress in network mode. You will find an area inside the Database Cache box on the General Settings page. Click ‘Enable database cluster’ to enable the functionality.
As for Memcached, W3 Total Cache recognizes the PHP module, so you need to install PHP Memcached. After that, you will be able to select Memcached as a caching method.
I hope this helps!
Thanks!

Hello Michael,

Thank you for the information.
You should try to manually remove any existing W3TC files and reinstall the plugin:
1. 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.
2. Delete wp-content files and folders
– cache folder
– w3tc-config folder
– object-cache.php (if exists)
– advanced-cache.php (if exists)
– db.php (if exists)
– upgrade folder
– delete w3-total-cache folder in wp-content/plugins/ (if exists)

3. Go to your wp dashboard and re-install W3 Total Cache

I hope this helps!

Thanks!

Hello SUngwook,

Thank you for reaching out and I am sorry about the issues you are experiencing.

1. I’ve tried to replicate this and I have no problems deactivating and removing either W3 Total Cache or Asset Cleanup plugin. Make sure that Minify is disabled for logged in users in Performance>Minify, save all settings and purge the cache and see if the problem continues to occur.

2. Try to manually remove W3 Total Cache:

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)
– db.php (if exists)
– upgrade folder
– delete w3-total-cache folder in wp-content/plugins/ (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

I hope this helps!
Thanks!

Hello Daniel,

If the issue persists once W3 Total Cache is completely removed then the issue is not related to our plugin.
I would suggest reaching to the support of the plugin you are using for bookings and your hosting support to check if there are any backups you could use.
Thanks!

Hello Danel,

Thank you for your feedback.
Please make sure that everything related to the W3 Total Cache installation is deleted:
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”.
Ensure that no residual entries are leftover in your .htaccess file after deleting the plugin.
2. Delete wp-content files and folders
– cache folder
– w3tc-config folder
– object-cache.php (if exists)
– advanced-cache.php (if exists)
– db.php (if exists)
– upgrade folder
– delete w3-total-cache folder in wp-content/plugins/ (if exists)

Have you tried clearing your MySQL table?

Thanks!

Hello,

Thank you for reaching out and I am sorry about the issue you are experiencing.
W3 Total Cache is compatible with the latest PHP 8 and this means that it’s also compatible with any previous versions.
I can see that you are using some other caching solution.
I would recommend completely removing and re-install W3 Total Cache. Make sure that the other caching plugin is completely removed as well.
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”.
Ensure that no residual entries are leftover in your .htaccess file after deleting the plugin.
2. Delete wp-content files and folders
– cache folder
– w3tc-config folder
– object-cache.php (if exists)
– advanced-cache.php (if exists)
– db.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.
4. Go to your wp dashboard and re-install W3 Total Cache
I hope this helps!

Hello Tim,

Thank you for the information and I am glad that you found the source of the issue.
You should keep it disabled in this case because it’s not recommended to use more than one optimization plugin.
Jetpack offers some minimal and basic optimization and since you are using W3 Total Cache you should keep this disabled.
Thanks!

Hello Pablo,

Thank you for reaching out and thank you for using W3 Total Cache!
I’ve replied to the topic you created in wp.org so please continue the correspondence there so we can avoid duplicating the answers.
Thanks!
