WordPress can’t find advanced-cache.php… can’t load any pages

There is supposed to be a blog here: lizrevision

For some reason, I got this error when i try to load any pages;

Warning: main(/home/sexydeci/public_html/lizrevision/wp-content/advanced-cache.php) [function.main]: failed to open stream: No such file or directory in /home/sexydeci/public_html/lizrevision/wp-settings.php on line 84

Warning: main(/home/sexydeci/public_html/lizrevision/wp-content/advanced-cache.php) [function.main]: failed to open stream: No such file or directory in /home/sexydeci/public_html/lizrevision/wp-settings.php on line 84

Fatal error: main() [function.require]: Failed opening required '/home/sexydeci/public_html/lizrevision/wp-content/advanced-cache.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/sexydeci/public_html/lizrevision/wp-settings.php on line 84

However, advanced-cache.php does exist and its permissions are set to 777.

Here is part of my wp-config:

define('DISABLE_CACHE', true);
define(’WP_CACHE’, true);

I have tried setting one or both of those to false but it didn’t do anything.
I can’t figure out what went wrong. Help?
