I followed the KB article for updating PHP4->PHP5 on Plesk 7.5.5+ (7.6.0 in this case) to the T. I get no output and no errirs from my php modules and was forced to revert. Reverting did nothing - no PHP scripts work at all now, and simply return a "404 not found" error for files I know are there. I seem to be up **** creek without a paddle at the moment. Any of you know how to fix this problem? I'd be happy back on PHP4 as long as it works.
