post the actual error message with debug mode enabled. If you can't go to coppermine's config to enable debug mode, use a database tool like phpMyAdmin, browse coppermine's config table and set debug_mode to "1" there. Posting a link to your page might help as well as upgrading to the most recent version (after doing a backup).
