On this site I run weblog with automatic updates enabled. I noticed, about a week or so ago, that I saw the following at the top of all of my pages:

define( ‘WPCACHEHOME’, ‘/home/bsdman/it.thelibrarie.com/weblog/wp-content/plugins/wp-super-cache/’ ); //Added by WP-Cache Manager

Well that’s less than fun, but I don’t really care enough to fix it. Unless that’s also screwing with the CSS and making it difficult to see the entire article under the theme I use… The scroll bar was present, but the bottom of the page cut off a lot of the instructions. Awesome.

Lots of searching and I find out that member “stealingsand” is very helpful. http://wordpress.org/support/topic/warning-wp-super-cache-caching-broken-the-script-advanced-cachephp-could-not

I performed the following:
SSH into your box
nano /weblog/wp-config.php

define( ‘WPCACHEHOME’, ‘/home/bsdman/it.thelibrarie.com/weblog/wp-content/plugins/wp-super-cache/’ ); //Added by WP-Cache Manager

This was listed at the top instead of after the ?php section. I just moved it down with the other defines, saved, and exited. Fixed!
