I really am beginning to wonder why this plugin gets the rave reviews that it does and whether or not you test before releasing updates.
I came home from a business trip today to find all kinds of disk warnings from one of my servers telling me that my temp files are nearly full.
While waiting for my tech team to delete what they said are literally thousands of temp files on the server, several of our clients sites are running into SQL issues. I can't update any plugins and I'm seeing error messages on some of the WordPress login screens.
We just starting using W3 Total Cache a couple of weeks ago on our clients' sites in attempts to reduce memory usage on the sever and quite honestly, it's been a nightmare from day 1.
