That stuff in the url I think is normal, because the search forum uses the "GET" method which puts all the info on the url. Hate to ask, but are you sure you're editing the correct file? (you said earlier that you edited the wrong one).

Also, if you have access to your web server error logs, check there.

Oh - another thing you could try, edit that file and put

die("This is a test");

right under the <?php at the top and see if you get that message.
