swp_cache_timestamp

can you help me with a message in all my pages, it says:

swp_cache_timestamp:
411372

It looks like it could be related to university theme as I'm seeing a fatal error with your theme:

PHP Fatal error: Call to a member function init() on a non-object in /nas/content/live/pucesa/wp-content/themes/University/functions.php on line 116

Please help me.
