For the last few days I've been religiously reading every unread post on the Forum. And the next time I login I see most of the ones I've already read, plus the new ones, with the result that my 'Unread Posts' list is now something like 30 posts long!
Hitting the 'Mark all posts as read' button at the end of a session produces this error message:-
And if I do re-login it says they're all marked, but I STILL get an ever increasing list every time.
It's getting past ridiculous now, so is it a known fault and if so, how do I fix it please?
