This forum occasionally forgets me - is it picking on me or just has amnesia?

Seriously I know it isn't picking on me.

Most of the time I come here, it's just fine. I go to my subscribed threads and if someone has posted after me the type darkened and I can click on it and go to my first unread post.

Most of the time when I come here I can click New Posts and see what happened since the last visit.

But every once in a while I come here and the forum tells me there are no new posts (I know that's a lie) and when I click to see my subscribed threads none of them are in bold typeface and my name isn't the last poster's name.

Now indeed it's a minor problem and I'm not getting bent out of shape about it. Just curious as to why. If it's on my end, I can fix it.

I've tried deleting cookies, erasing history, and using a browser cleaner to erase all traces of the forum. This doesn't make the forum forget me, because time after time of trying this it remembers. Then all of a sudden it will forget.

I've tried using Chrome and Firefox browsers with the same results.

So why is the forum occasionally forgetting me?

Does it happen to anybody else?

Could it possible be on my end? If so, how can I fix that?

Like I said, I'm very curious as to why this happens. I frequent other Powered By: vBulletin forums that don't forget me.

And again, I'm not losing any sleep over it.
