Sorry...
You'll need to make sure that mainfile.php is chmod at least 644 (perhaps even 666) before you make changes to it, otherwise the changes will not take effect. If your host uses Windows, you'll need to remove the check box on the Read-only attribute.
I hope this clarifies things.
Best Regards,
James
Insanity can be defined as "doing the same thing over and over and expecting different results."
Stupidity is not a crime. Therefore, you are free to go.
