Re: Tags not found
If you changed from 1.3 to 2.2 in Apache and it worked before the upgrade, it must have something in there that it doesn’t like with the Mod Rewrite handling. I am not sure myself, but I would change my .htaccess in the bbPress root folder of http://www.canadianbookclubs.com/forums/ to have only:
Options +MultiViews
Nothing else. Try it in that and in your http://www.canadianbookclubs.com/bkrv/ test run with the new version as well. Either way, it should work for one of them. That works best with most servers I have used and they are using Apache 2+. Try that out maybe and if not, take Fel64’s suggestion and put the contents of what is outputted by: /bb-admin/rewrite-rules.php
