Today when I logged in to the forums my inbox was empty, which was a surprise because I follow a bunch of spaces and usually there are about 30 items in my inbox in the morning. Even when I unchecked the "Unread Only" box still nothing was in my inbox. Looking at the discussions page I see that there are new discussions in spaces I am supposed to be following, but none of them went to my inbox. When I go to the Places link in my profile it still shows that I am following all of the spaces and groups, but if I hover over a space name that I was following, it gives the Follow link as if I am not following it anymore. If I try to follow it again I get the following error message:

Clicking the link to refresh the page did not help, nor did logging out and logging back in, nor did clearing my browser cookies and cache. Anyone know what's going on?

I'm hoping this is a temporary issue. It happened once before to me one evening about a week ago but was fixed the next morning.
