Forum Really Annoying ERROR !!

[محروم.كوم]

Hi,

I'm continually getting the below error. This is emailed to my administration email at least 30-40 times a day.

It seems to appear when comebody has clicked the 'what's new' button on the navbar, or else when somebody searches for posts by a particular user, or latest posts.

If I 'Rebuild forum information' in update counters, the 'what's new' function seems to work for one click and then goes back to 'posts not found' or even a database error page.

This is really frustrating and I'm not sure what to do about it.

Very grateful for any help.

Here's the error:
