I am getting this page not found error and its driving me nuts, it works if I check the turn wordpress into wpforo but not with the community address.... please help.  website is btdtwebsite.com

Please remove all forum pages, then navigate to Dashboard > Plugins and Uninstall (not delete) wpForo. It'll remove all wpForo settings and content. Then install it again. Make sure you use WordPress permalinks something like /%postname%/ or else in Settings > Permalinks admin page, it doesn't work with default ?p=1 url structure.

That was perfect! Thanks Robert!
