Recurrent bug – You are not authorized to see that page” is displayed to our users

Hi !

We implemented the DW Q&A plugin in our website for our users community to share links between them.

This works fine, only that some users cannot access to the page where the plugin is embedded any more. They have a message saying there are not allowed to see that page.

We found a fix for that (save the permission again without any modification), but the bug comes back after a day or two.

A user found a fix by going to his user profile and doing the same, i.e. saving it without any modification. This fixes the issue temporarily.

Any idea how to stop this recurrent dysfunction ?

Thanks in advance !
