Can't follow my own topic

Until some weeks ago I was following my own topic (http://www.computercraft.info/forums2/index.php?/topic/18156-mc-16-cc-158-163-turtle-chunkloaders-mining-chunkloaders-crmod/) without problems. Then I stopped receiving notifications (the first I didn't receive was the 15th of July). I noticed I'm not following the topic anymore so I tried following it again: I press the "follow this topic" button, then the button in the window but nothing happens, the button remains "follow this topic" and the counter doesn't change. If I click again it acts like I'm following the topic. If I refresh the page it's like the first time. In the "Content You Follow" page my topic isn't listed. I tried following other topic and it seems to work.

I've had this issue before. I have no idea how to fix it…

I've had the same issue too.

I'd like to add that I'm seeing not only this problem but an additional issue that may or may not be related. I am unable to follow my ccDHD thread, and additionally, it often displays as 'read' to me even though there are new posts.

I've had issues where a topic is displayed as "read" too, but I don't think that this is related (although, I cannot confirm that). I've actually googled this problem and found that other IPB forums are acting the same, but no one seem to know what's causing these issues.
