Plugin 1.1.20 doesn't work for me (WP 3.9). A 403 Forbidden error page shows after pressing "Publish menu". I've got 403 Forbidden error page even after pressing the "Hide Notifications" button on settings page.
Changing all plugin's files and folders permissions to 777 didn't help.
This cannot be hosting problem because of hundreds of WP sites working there without any troubles. Even so I did check another hosting and the error was the same.
I'd like to give AWM a try but I have wasted a lot of time so far.
