Troubleshooting Guide

PHP and CGI problems:

• "Internal server error": Apache refuses to run any CGI program (notably php.cgi) which is group-writeable or world-writeable, or which is inside a group- or world-writeable directory. Fix directory permissions.
• "Internal server error": php.cgi has been corrupted by downloading/uploading as an ASCII file. Replace php.cgi per FAQ.
• "Internal server error": cgi program does not have executable bit turned on.
• "Internal server error": cgi program does not start with correct hash-bang line such as "#!/usr/bin/perl".
• "404 Not found" when trying to use /tools/ or a PHP program which does in fact exist: php.cgi has been deleted. Replace php.cgi per FAQ.
