Caching Plugin Not Working

Hello @johnwwr

Thank you for reaching out and I am happy to assist you with this.
I’ve checked your website and indeed there is an HTML snippet in the source of the home page which suggests that W3 Total Cache is active.
Once I bypassed the cache, the page loaded without the mentioned snippet.
Most likely, you’ve installed the other caching plugin before removing the W3 Total Cache and the homepage was cached with this and continues to be served from the cache.
You should make sure to remove the following 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)
– 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.

Make sure to purge the cache of the other plugin you are using and any server-side cache.
Also, let me know if you want to re-install W3 Total Cache as the most complete caching solution and optimize your site for the best possible performance as no other plugin can compare when it comes to the optimization possibilities with W3 Total Cache.

Thanks!

Hi

I don’ see how create a new topic so let me ask questions concerning my W3TC configuration. I have 2 error messages :

W3 Total Cache error:It appears Minify URL rewriting is not working. Please verify that the server configuration allows .htaccess
Unfortunately minification will not function without custom rewrite rules. Please ask your server administrator for assistance. Also refer to the install page for the rules for your server.
Infos techniques

.htaccess file contains rules to rewrite url https://bluelight.blue/wp-content/cache/minify/984627727w3tc_rewrite_test.css. If handled by plugin, it returns "Minify OK" message.
The plugin made a request to https://bluelight.blue/wp-content/cache/minify/984627727w3tc_rewrite_test.css but received:
Array
(
    [code] => 500
    [message] => Internal Server Error
)

instead of "Minify OK" response.

Thanks for help !

Hello @luz7

Thank you for reaching out.
Since this is a separate issue, please start a new thread here as these issues are not related.
Thanks!

@vmarko thank you for your response, appreciate it.

I have followed your instructions and nothing has changed unfortunately.

You should make sure to remove the following wp-content files and folders:
– cache folder (done) 
– w3tc-config folder (done)
– object-cache.php (if exists) (done)
– advanced-cache.php (if exists)(done) 
– db.php (if exists) (done)
– upgrade folder (done) 
– delete w3-total-cache folder in wp-content/plugins/ (if exists) (done)
– Delete Cached Files from CDN (if using CDN)

(I do not use a CDN)

To complete the above, I downloaded the plugin ‘file manager’. Searched for each file and deleted it. I purged all cache with Nitro and now no new files for the cache have been created.

My page speed remains the same, so I assume nothing has changed. Any suggestions?

If you put my site through GT Metrix you will see it takes 2.3 secs* to initial load

Hello @johnwwr

With the steps provided, you removed W3 Total Cache completely including all drop-in files and configuration files.
As I can see now, the HTML snipped is gone and the website is no longer cached with the W3 Total Cache.
As for your page speed, I am unable to assist you with this since you are no longer using the W3 Total Cache plugin. Using more than one optimization plugin is never a good idea simply because of the conflict that can occur, and one of the examples was the conflict you have had.
What I can advise you is to ONLY use W3 Total Cache and remove any other plugin you are using for the optimization, including the plugin you currently have installed. W3 Total Cache is the most complete caching solution and when configured properly, it will deliver the best performance and speed for your website.

Let me know if you have any other questions.

Thanks!
