 * Your theme is calling a function that doesn’t exist on your system, which is 
   odd because the function is a core WP function beginning, looks like, in WP 2.7.
   Either, you haven’t uploaded all of the WP files or you are using a WP version
   older than 2.7. What version of WP are you using?

 * 2.6.5. i’ll try to update it, but it gets me nervous.

 * Backup everything and [follow the instructions](http://codex.wordpress.org/Upgrading_WordPress_Extended)
   and you should be fine. Its probably a good idea to upgrade to 2.7, then go to
   2.8 rather than try to jump straight to 2.8.
