Rick, I am having this problem right now too. I did just move the site to a new server. We can use the quick search but not the advanced search, it effects everyone, users, admin, etc.

I am using forum version 7.5.3 and I don't see the run permission check tool in the lower part of the cp menu.

I was a bit worried about deleting all the files in the templates/compile directory. There is even and index.html file in there. Can it cause any problems to remove any of these files?
