I was following Tom Geller's training on the Testing module, so I thought I'd give it a try.
I turned Testing under Modules.
Next, I looked under Configuration, but Testing was not there.
I should preface this with the fact that when I first Saved after turning on the Testing Module, I got:
"Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 24 bytes) in /home/plainen2/public_html/includes/menu.inc on line 3683"
but, then, it seemed that my checkmark persisted.
What should I do to fix this?
