After I purchased Front End PM PRO, and uploaded and activated it (also deactivating the free version), I have lost the following options.
Disable Auto-suggest in To Field.
Only allow messages to Admins.
I do remember seeing these, even if they were not selectable because they are PRO options, they were visible as a way of showing what options would be available for PRO users. Now that I’m a PRO user, I can’t find these options anywhere. I need to be able to prevent users from sending messages to anyone but admins and these two options seemed like the way.
