Topic: Search brokeded

Getting these errors on my search page:

Notice: Undefined variable: show_as in /home/*****/public_html/search.php on line 110

Notice: Undefined variable: action in /home/*****/public_html/search.php on line 119

Don't know when it happened, or how.
Would assume it's an extension doing it.. but is there any quick and easy way of finding out what is?

So I wouldn't have to go through disabling each extension? >.<
(My tick boxes don't even work when trying to disable/enable multiple extensions. sad)
