Suddenly all the custom CGI of the server are returning on 500 Internal Server Error.

All the cgi from cpanel are still fine.

Any idea?

Thanks

Make sure they are chmod to 755 and (if suexec is enabled) all the directory structure leading to there path is set to 755. Also make sure the CGI scripts are uploaded in ASCII transfer mode. You may need to consult the errorlog for more information, or the suexec log if suexec is enabled on your server (I'm assuming it is).

All the CGIs are old scripts that were in use in the server for months.

After some security changes it stoped running.

you may want to check the owner of scripts. using chown command for fixing it if it's wrong.

Also check to see if an .htaccess file exists in the directories.

Depending on your Apache setup, there are a few directives you can add to .htaccess that will cause a 500 error.

If the file exists, try temporarily renaming it and seeing if the error goes away. If so, a little troubleshooting should find the offending section(s).

Thanks!

What security changes were they? Roll it back. It could also be mod_security ot one of those modules added. Try disabling that module and see if that's the cause of your problems.

If you want I can take a quick look for you.
