advanced-cache.php was edited or deleted...

[richardfoley]

Talking about getting frustrated. Tried to turn Simple Cache on, and received a non-useful error message:

wp-content/advanced-cache.php was edited or deleted. Simple Cache is not able to utilize page caching.

I am expecting SC to create this file for itself, permissions are fine, and if SC can't find it's own advanced-cache.php then where should I pull it from..., best guess? Clicking the Fix button, just redisplays the same error message. Hmmm.

Same here. What's this stupid bug?

Mind giving some details on your environment?

Basically sounds like some permissions or a conflicting plugin which also makes use of the advanced-cache file (or tries to keep it away as it would conflict).

Have seen it happen with WP-Rocket but that's just common sense. You need to make a choice in who will do the disk file based actions basically.
