I had the exact same problem, except after commenting out the “catchbox_sliders” function, I kept getting syntax errors for unexpected end of file. I’d go to the line specified and comment it out or add a ?> tag, but then another line would show up.
I’m completely hosed at the moment. I may have to go through my FTP client to delete the entire theme folder.
Did you bother to test this latest update? (Just curious.)
