500 error with GoDaddy’s form mail

I was getting a 500 error when trying to submit a form mail from my web site via GoDaddy’s gdform.cgi. I turned on error logging and this is what showed up:
SoftException in Application.cpp:624: Could not execute script “/home/content/a/r/d/ardamis/html/cgi/gdform.cgi”
Caused by SystemException in API_Linux.cpp:430: execve() for program “/home/content/a/r/d/ardamis/html/cgi/gdform.cgi” failed: Permission denied
