Cache error?

First off, hey everyone, love WP and these support forums are teh win. ??

Now on to business.

Basically I’ve been testing the beta on my live blog since beta-1 (don’t really much care about random breakages and the like), the only real WP related problem I’ve had is the new caching system. It works and all but whenever I try to upgrade I have to go to wp-settings and comment out lines 65 and 66 so that my blog can be accessible.

The error is as follows:
Warning: main(/homepages/27/d89355863/htdocs/blog/wp-content/advanced-cache.php): failed to open stream: No such file or directory in /homepages/27/d89355863/htdocs/blog/wp-settings.php on line 66

Fatal error: main(): Failed opening required ‘/homepages/27/d89355863/htdocs/blog/wp-content/advanced-cache.php’ (include_path=’.:/usr/local/lib/php’) in /homepages/27/d89355863/htdocs/blog/wp-settings.php on line 66

And here’s the offending (and surrounding lines):
// For an advanced caching plugin to use, static because you would only want one
if ( defined(‘WP_CACHE’) )
require (ABSPATH . ‘wp-content/advanced-cache.php’);

Like I said, after commenting out those 2 lines it seems like everything is working. The wp-content/cache folder is created and seems like it’s being updated as it should. Just to test things out I installed a fresh beta WP and never got that error at all. So I’m assuming something got borked when I first upgraded from 1.5.2 to the first beta.

Oh well, my “fix” does the job for me, just figured I’d bring it to someones attention.
