Fix HTTP Error 500 in Perl Script

If you receive the error message HTTP Error 500 (Internal Server Error) when you call your script, make sure that your program has the following points:

  • Please set the execution rights for users (705 or 755).
  • The first line in the script is always #!/usr/bin/perl.
  • Always insert a backslash (\) before the @ sign (e.g. in email addresses) (unless the @ sign is in a string with single quotation marks). This is necessary because the @ character in Perl is reserved for the names of arrays.
