Thanks, but that didn't do the trick.
I got a response from the person who had the same problem and fixed it. His advice didn't do the trick either. His advice was:
Sure, just go to the ACP and under Maintenance click Repair / Optimize tables then select threadviews and make sure both options are selected as yes, (I think they are by default) and click continue.
I have a big board (with about 15k members) and my forum looks just horrible. Here's an example of how bad it looks when the views counter isn't working:

Any more ideas would be appreciated, I'm quite frustrated with this minor bug.
