Any Perl or CGI scripts that you upload to your cgi-bin need to have the 'execute' permission set. If this is not done you will receive an error message in your web browser that you don't have permission to access the script when you attempt to run it. Most FTP programs have an option that lets you set execute permissions for files that you upload. If
yours does not have this option you can enable execute permission for your scripts by choosing this option. You can use this option to set execute permission for ALL CGI scripts in the CGI-BIN or you can use the "Set file permissions on any file" option in the Control Panel to choose the permissions you set for specific files.
Clicking the Set all cgi-bin programs executable button will turn the 'execute' permission on for ALL CGI scripts in the CGI-BIN.
