Cache in CPanel – WP-Content-Cache Filling Up

Since installing Quick Cache I’ve been having problems with 403-Forbidden warnings with some of my sites.

I contacted my host and they had to clear out the WP-Content–>>Cache folder. I had the problem again this evening after checking the plugin configuration and using all the recommended settings.

After the 1st instance today I place caching on Automatic.

Tonight when the problem reoccurred I went into the server folder and cleared it and the site came back.

Is this something with the plugin or another issue? It’s a WordPress site and as I mentioned I didn’t have this problem previously.

Thanks for any assistance,

Don

Hello Don,

That’s very strange, Quick Cache doesn’t do that. I would check a couple of things:
First, make sure that you don’t have another caching plugin besides Quick Cache installed.

Second, do a compatibility test, change your theme back to the default theme (TwentyEleven), and also disable all your plugins except Quick Cache (and s2Member if you have it) to test if the problem goes away.

If your website already has visitors, then I suggest you do this in a test environment, simply install WordPress and Quick Cache alone, if the problem doesn’t happen, then it means there is an issue with another plugin/theme you have installed.

Hope this helps. :)

Instead of turning everything off and switching themes I started with a simpler approach first.

I have 20 sites. In the two that have been having this problem I turned off Quick-Cache and the other left it on.

Over night I let everything run and this morning the site with the Quick-Cache deactivated had an empty WP-Content–>>Cache folder.

In the site with the plugin on the WP-Content–>>Cache folder had a number of items in the folder, not too full to forbid access to the site. I went into the site WP admin and manually hit the “clear cache” button, return to the respective WP-Content–>>Cache folder and reloaded it. It was now cleared except for qc-1-mutex.lock.

I perform this exercise in two other sites and the respective WP-Content–>>Cache folder was cleared only after manually clearing the cache in the WP-admin for those sites.

It looks like Quick-Cache is not automatically or otherwise clearing the cache.

Hello Don,

Well, I can’t seem to find anything related to completely clearing the cache, I can only find things related to refreshing the cache in order to make sure the content is up-to-date.

Just wondering, how many pages/posts or other types of content do you have in those websites? It might be that Quick Cache is trying to cache everything, and it needs tons of space for it.

If you don’t have a lot of pages, then I don’t know what it could be, while Jason checks this (I’m sending him an email) you think you could manually clear the cache?

These are young sites I’m discussing. One has 14 posts and 34 pages. Comments are closed. And while I’m checking the number of posts/pages on the other site I’m testing, the one with the plugin still activated, I received the “Forbidden – Site Not Available” in the browser.

After clearing the cache in the CPanel I’m now able to get into the WP Admin area as the site came back. See cache screenshot below.

That site contains 14 posts and 48 pages, comments closed. Isolating the two sites, one with the Quick Cache on/one off the one using the plugin is not working correctly.

OK Don,

I notified Jason soon after posting my previous post.

Remember that Jason is only checking his email around once a week or less.

For now I’m deactivating all Quick Cache plugins. Thanks for your assistance.

Thanks for the heads up on this thread.

This sounds like one of three things are happening.

1. Your Quick Cache configuration, regarding “Cache Expiration Time” is too high?

2. Or, it’s possible that these installations of WordPress do not properly support the WP-Cron class, making it impossible for Quick Cache to automatically clear the cache at regular intervals (i.e. behind the scene). This would be a question that I would present to my hosting company. (i.e. Is WP-Cron enabled?)

3. The /wp-content/cache/ directory is not readable/writable by the server itself? I doubt this is the case, since you said that a manual cache reset does work properly.

Cache expiration time is set at the default 3600.

Permissions on WP-Content–>>Cache is 755

In WP-Cron is this the php file?? I went into those permissions and they are set at 644.

If your talking about something else as you mentioned “enabled” is this something I can change or does the host need to implement this?

Thanks,

Don
