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 Lethicia,

Thank you for yoru question and I am happy to answer.
We are already in the progress of testing the latest Divi release and making sure that the Article is up to date accordingly.
The information from Divi is related mostly to Divi files and not taking into consideration any additional plugins the users may or may not have. This is where W3 Total Cache comes to the rescue.
Thanks!

Hello Emiliano,
Thank you for your question and I am happy to help!
I’ve checked your website and after inspecting the source I can see the following header:
last-modified: Thu, 19 Aug 2021 22:04:02 GMT
I can also see Status Code: 304
This being said, the last modified was almost 24 hrs ago.
Can you please confirm you are still seeing the last-modified header changing every hour?

Thanks!

Hello Shannon,

Thank you for reaching out and I am happy to assist you with this.
Short answer -yes. In wp-content/plugins/w3-total-cache/w3-total-cache-api.php you can find the purge functions.
In your case:

function w3tc_flush_post( $post_id, $extras = null ) {
	$o = \W3TC\Dispatcher::component( 'CacheFlush' );
	$o->flush_post( $post_id, $extras );

or you can call flush for the URL:

function w3tc_flush_url( $url, $extras = null ) {
	$o = \W3TC\Dispatcher::component( 'CacheFlush' );
	$o->flush_url( $url, $extras );

As you can see you can call w3tc_flush_post( $post_id ) or w3tc_flush_url($url)
I hope this helps!
Thanks!

Hello Mike,

If the plugin is not in the “Installed plugins” list, this means that W3TC is not installed.
Have you tried re-installing W3 Total Cache by adding a new plugin?
Thanks!

Hello Steven,

Thank you for reaching out.
As this is a public forum, I’ve deleted the license from the topic.
I can see that the license key is applied to your website.
If you still do not see the W3 Total Cache Pro activated, 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!

I’ve also replied to your email via the support channel. Please continue the correspondence there so we can avoid duplicating the answers.

Thanks

Hello Nicholas,

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

As per Woocommerce, it’s advisable to exclude the cart and checkout from caching and minifying in W3 Total Cache(this depends on the settings you have enabled)
So you should add /cart/  and  /checkout/ in Performance>Page Cache>Advanced>”Never Cache the following pages” and in Performance>Minify>Advanced>”Never Minify the following pages” filed. Make sure to save all settings and purge the cache once the pages are added to the filed.


It would be great if you could share the website URL so I can check for any console errors.

Let me know if the provided suggestion helps!

Thanks!

Hello John,

Thank you for your question and your interest in W3 Total Cache Pro!
You should have no problem running Pro on your Dreamhost!
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.

Thank you!

Hello Daniel,

Thank you for reaching out and I am sorry about the issue you are experiencing.
I am not familiar with the plugin you are mentioning so can you please share the URL of the RDV plugin?
I did my best to translate your message, however, I am still not sure what the exact issue is.
To confirm, once you completely remove the W3 Total Cache and reinstalled the plugin you are using for those appointments the issue continues to persist?
One more question is does this happen in the wp dashboard or on the website? Or to be more specific, for logged-in users?
Thanks!

Hello Sephan,

Thank you for your inquiry and I am happy to assist you with this.
When using cache Preload in W3 Total Cache, depending on how big your website is and on the settings it may take some time for the entire website to be preloaded.
What the Cache preload does is:
– Check the last offset
– Check how many URLs are allowed to be processed per run
– Fetch all URLs from sitemap (even nested sitemaps work)
– Loop through a set of URLs to visit them
Your sitemap URL should be added like this: https://yourwebsite.com/sitemap_index.xml
If the end of the list is reached, it will start from the beginning of the next run. That means that when the last page is reached, it will start from the beginning with the first 10 pages and so on (10 pages if the default values are set).
If you have your site set to use wp-cron the default way (native wp-cron), it only triggers visits to your site. WP allows you to turn this offdefine('DISABLE_WP_CRON', 'true'); so u can trigger wp-cron.php manually via your system’s cron. When you do it that way the preload will run in batches on each cron job call to wp-cron.
WP-CLI can also be used for priming and logging. If you don’t want to rely on wp-cron – use the wp-cli command for preloading and Unix cron. You should call it directly in wp-cli wp w3-total-cache pgcache_prime
and track the output which pages/sitemap positions are primed by script.
I hope this helps.

Hello Tim,

Thank you for reaching out and I am happy to assist you with this.
I’ve checked your website and browsed through your website and I can see all the images loading correctly – no broken links.
Since this only happens on your computer it’s unlikely that it has something to do with the W3 Total Cache. Have you tried clearing your browser cache or check the website in some other browser and see if you are experiencing the same issue?
Let me know if this helps!
Thanks!

Hello angel,

Thank you for reaching out and thank you for using W3 Total Cache.
I’ve tested your website and as I can see, the one thing that impacts your website scores the most is your images. Google is suggesting optimizing images and serve them in the next-gen (webp) format.
Since this is currently out of W3TC scope, I would suggest using some image optimization plugins like Ewww image optimization or SmushIt and use one of the mentioned plugins to optimize your images.
I hope this helps!
Thank you!

Hello Mario,

I am sorry about the issue you are experiencing with installing W3 Total Cache and I am happy to assist you with this.

Server Error 500 Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator to inform of the time the error occurred and of anything you might have done that may have caused the error. More information about this error may be available in the server error log.

Have you tried reaching out to yoru hosting provider and check the error log to see what may be causing the issue as suggested in the “Installation failed error”?

You can try to manually install the plugin:
1. Download the plugin here. It will create a Zip file/archive to send to your computer.
2. Log into your WordPress admin site and go to the Plugins section.
3.Click on Upload and select the zip file. WordPress will unpack everything and put files in the right place.
4.Activate the plugin.

You can also try unzipping the file and manually upload the folder to /wp-content/plugins/ and then go pack to your wp-admin area, go to installed plugins and activate the plugin there.

I hope it helps!

Thanks!

Hello KT,

Thank you for your question.
The Garbage collection interval is there to delete any _old files that are being created after the cache is purged.
So once the cache is purged if the Garbage collection interval is set to 3600s, all _old files will be deleted from the server after one hour.
Thanks!

Hello Warren,

Thank you for your question and I am happy to assist you with this.
I am sure you understand that we cannot test W3 Total Cache with all plugins out there so I cannot give you a straightforward answer.
I’ve never heard about the plugin you are mentioning before. Can you please confirm this is the plugin you are referring to:

Threepress

In order to find out which W3TC setting might be causing this, 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.
Thank you!

Hello Mert,

Thank you for reaching out and for using W3 Total Cache!
It would be great if you could share your website URL and your test results so I can check this.
As I understand the problem is in your wp-admin area where you are experiencing a long waiting time?
Thanks!

Hello Jose,

Thank you for reaching out and I am sorry you are experiencing the issues installing W3 Total Cache.
The issue is most likely related to your server files/folder permissions or dis quota.
Login to cPanel or your web hosting dashboard and check the disk quota and make sure you have the correct write permissions set on your server (files 644 and folders 755)
Alternatively, you can try to manually install the plugin:
1. Download the plugin here. It will create a Zip file/archive to send to your computer.
2. Log into your WordPress admin site and go to the Plugins section.
3.Click on Upload and select the zip file. WordPress will unpack everything and put files in the right place.
4.Activate the plugin.

You can also try unzipping the file and manually upload the folder to /wp-content/plugins/ and then go pack to your wp-admin area, go to installed plugins and activate the plugin there.

I hope it helps!

Thanks!

Hello Lisa,

This is how W3TC works.
It appears that only the Super Admin is able to access it in your case.
Thanks!

Hello Lisa,
It would be great if you could share some screenshots of what you are seeing on the W3TC settings page on one of the subsites.
This is how it supposed to look like for example (Please note that in this case the option Use single network configuration is enabled and you can see the “Use specific settings” button )
