When I try to save the changes for my forum subscription automated mail, I get the following:

Warning: main(modules//.php): failed to open stream: 
No such file or directory in /home/httpd/vhosts/msx.org/httpdocs/modules.php on line 17

Warning: main(): Failed opening 'modules//.php' for inclusion (include_path='.:/usr/lib/php/:/usr/share/pear/') 
in /home/httpd/vhosts/msx.org/httpdocs/modules.php on line 17

Greetings.

Thanks for reporting the problem. At the moment I have some other things on my mind, but I'll try to fix things as soon as possible.
