What version of PHP are you running with Plesk 7.5 on Fedora Core2 ? And did it come that way or did you upgrade PHP ? If you upgraded did you use the php sources and compile it or ART ? I have a customer with some very stringent requirements on PHP and GD libraries. I think there may be a bug in the current RH9 PHP 4.3.2 that is causing some headaches with one of their classifieds applications.
