The mother of all errors! Knowing what the file permissions need to be is critical for your PERL applications to function. You’ll need to refer to your program’s documentation to learn what permissions need to be set for which files.
Do NOT set permissions on any file that resides within your cgi-bin directory to 777 (rwxrwxrwx). Use 755 (rwxr-xr-x) even if the program’s documentation calls for the 777 permission.
