CDN Stopped working suddenly…?

(Visiting an image URL and adding cdn. to the start of the URL loads the image from the CDN, it seems to be a front end issue causing the content to be loaded locally rather than from the CDN.

Many thanks in advance for any help.

On further investigation it seems the plugin is actually not working at all… js/css is not minified anymore either.

No errors in the dashboard, I’ve checked that the .htaccess is ok and it matches a backup file from last year.

WP_CACHE is switched on in config too.

Should there be anything in mu_plugins folder?

I have a ‘object-cache.php’ and ‘advanced-cache.php’ file in wp-content – should there by any other w3tc related files?

Many thanks.

Hello @flashjunkie

I am sorry about the issue you are experiencing and I am happy to assist you with this.
This is a very strange issue also, so the question is have you made any changes on your server prior to this issue?
I’ve checked your website and I can see x-powered-by: W3 Total Cache/2.2.4

Besides the ‘object-cache.php’ and ‘advanced-cache.php’ files in wp-content which are the drop-in files (meaning you are using Page Cache and Object Cache feature in W3TC), there should be a w3tc-config folder with the master.php files that contain the entire W3TC configuration, and of course, the cache folder where w3tc stores the cache and minified files

You are mentioning the .htaccess ut as I can see your website is on the Nginx platform: server: nginx
Have you recently changed the hosting provider or a hosting pan or have any similar steps been taken before the issue started to occur?

Thanks!

Just to keep this thread updated whilst I await a reply.

I have completely cleared and deleted the plugin and reinstalled, still not behaving as though it is installed… no HTML comment visible when enabling the basic page cache.

I have reimported my settings and same result, the plugin behaves as though it is not installed…

Hi Marko,

Thanks for replying, we have been working on some website updates but front end changes. No server changes.

We have been on the same server since 2019, the only plugins installed recently are UBERMenu plugin.

The files you mention are present and correct as is the config folder.

Many thanks

I’ve checked your website and I can see x-powered-by: W3 Total Cache/2.2.4

I’m not seeing this comment on my end…?

I’ve seen this in the response headers now.

Further indication that the plugin is not working, the minify folder is empty, only a index.html file is present. I have tried a few times to rebuild the minify cache.

Hello @flashjunkie

Thank you for your feedback.
It seems that the rewrite is not working as it should. Check the nginx.conf rules in Perofrmance>Install and see if those rules are applied in your nginx.conf file.
Since your website is on Nginx, potentially you need to restart the Nginx in order for the changes to take place.
Let me know if this helps!
If the issue persists, drop us a note via the plugin in Performance>Support.
Thanks!
