While that can be quite a fright to have that happen, StudioPress has no control over how your theme works on your site. :) In other words, we can't disable it on you.
It looks like some of the files on your server got deleted or corrupted. Can you look at the theme folder via ftp or your website control panel? You will probably need to reinstall the theme.
