Hi Salik,

Thank you for your inquiry and I a happy to assist you with this.
W3 Total Cache also has an X-Frame-Options in Performance>Browser Cache>Security Headers and you can choose the directive.
Can you please confirm if the option is enabled as it may be causing conflict with your directive?
Also can you please share the website URL and how you added the directive (.htaccess/nginx)?
Thanks!

Hello Vadym,

I am sorry about the issue you are experiencing and I am happy to assist you with this.
When did you start to experience this issue?
Have you made any recent updates or similar? Have you tried purging the cache and see if the issue persists?
The “Skip to content” comes from your theme and is often hidden from view and used as an accessibility enhancement that lets keyboard users and screen readers jump from the top of the page to the content without having to go through other elements on the page first. So most likely the page was cached and purging the cache should solve this.
Thanks!

Hi Fahad,

Can you please share which settings you have enabled in Performance>General settings?
Have you tried disabling minify (if enabled) and see if the issue persists?
It would be great if you could share the website URL and please feel free to drop us a note via the plugin in Performance>Support.
Thanks!

Hello Brian,
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 Sean,

Thank you for your inquiry and I am happy to answer.
W3 Total Cache is a separate plugin and Premium BoldGrid Connect does not include W3 Total Cache Pro.
As a separate plugin, it requires a separate license.
Thanks!

Hello Celine,

Thank you for your inquiry and I am happy to assist you with this.
You can use w3tc_flush_all
You can check more functions in wp-content/plugins/w3-total-cache/w3-total-cache-api.php
In this case the function:

/**
 * Purges/Flushes everything
 */
function w3tc_flush_all( $extras = null ) {
	$o = \W3TC\Dispatcher::component( 'CacheFlush' );
	$o->flush_all( $extras );

Thanks!

Hello James,

I am sorry about the issue you are experiencing when upgrading the W3TC and I am happy to assist you with this.
What you can do is to make a backup of wp-content/w3tc-config/master.php and completely remove and re-install W3 Total Cache following the instructions below:
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/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
7. copy and paste the backup of master.php to wp-content/w3tc-config/

Alternatively, you can try upgrading the plugin to 2.1.1, download the latest version from here and copy the \w3-total-cache\lib\Minify\Minify\HTMLTidy.php from the downloaded folder into /home/xxxxxx/public_html/wp-content/plugins/w3-total-cache/lib/Minify/Minify/
I hope this helps!
Thanks!

Hello Dominique

I am sorry about the issue you are experiencing and I am happy to assist you with this.
We have an open issue in our Github Repository, regarding this problem. Please make sure to track the progress of the issue regularly and feel free to commend on it and share more info.
Thanks!

Hello Lian,

I am sorry about the issue you are experiencing and I am happy to assist you with this.
I’ve checked your website and I am not seeing any issues, or better said, I don’t know how it supposes to look like.
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?
If for example minify is causing the issue, re-enable minify, and disable the settings in Performance>minify one by one (HTML minify, JS minify, CSS minify) and see which one might be causing the issue.
Make sure to save all settings and purge the cache after each option is disabled.
Thanks!

Hello Mike,

Thank you for the information.

Does this always happen when logged in or have you checked when logged out from the wp-admin?

Thanks!

Hello Avi,

As I already replied via the support channel, this depends on what changes you are making in the backend. When installing new plugins or removing the unneeded plugins it’s recommended to purge the cache.

However, if you are referring to updating the posts or creating new articles then no, there is no need to purge the cache manually as it’s being handled by the Purge policy in Performance>Page Cache so the cache will be cleared automatically.

Thanks!

Hello Tim,

Thank you for your questions and I am happy to answer.

1. 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.
2. 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 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

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 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 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 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 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!
