Try cranking your error reporting level up in php.ini

http://uk2.php.net/manual/en/ref.err...rror-reporting

Check the display_errors directive while you're at it. Don't forget to
restart the webserver.

Also, sometimes errors don't show because they're embedded in HTML. Eg
<font face="<? echo($fake_variable); ?>"> would return
<font face="<br /><b>Notice</b>: Undefined variable: fake_variable in
<b>file.php</b> on line <b>1</b><br />">

And you'll have to examine the un-parsed HTML to find the error.

Yeah, that did it, thanks
