If your Perl scripts are returning a 500 Internal server error, most likely related to one of the following:

1. Have you installed the Perl valueapp? If not, login to your control panel and under the side menu "ValueApps" OR "Install & Manage" and under "Web Development", install the Perl valueapp.

2. Set the script's permissions to allow it to execute using the command/settings chmod 755.     (E.g. $chmod 755 test.cgi)

3. Make sure that the interpreter designation (first line of the script) is correct and has the correct path - usually it is #!/usr/bin/perl. You can search for the perl directory to make sure.
