CMS Made Simple Forums

Hi,
I like those "Mark as read" buttons in forums. Unfotunately, I cannot use it here for ALL forums (the global button on the start page of the forum). I get the following error:

Session verification failed. Please try logging out and back in again, and then try again.

Does anyone know about it?

It does it to me too, but when it give you that error it gives you a link to see all of your unread posts. If you click that link and then click "Mark As Read" it pretty much does what you are looking for.

Okay, but I found only a Link for unread posts separately for each section. So I have to do that three times to mark all posts. but - it works, thank you

Attached is a series of Screenshots with the process I took. I only had to do it once for the whole forum.
