XF 1.2 How To Rebuild Discussions & Messages


Active member
Can anyone tell me please how to rebuild the Discussions & Messages count of a forum on the index page?

I had a forum with many threads in which i deleted a day or so ago but it still says on my index page that there is Discussions: 888 Messages: 889 in that forum when there isn't there is only 3 threads.

Can anyone help please?
