Ok I finally caved and mirrored my site and started a upgarde process so see how it would go on my live site.

Everything seems to be ok... except upgrading to the latest CBB 2.x from CBB 1.15.

You can go to the main forum listing and topic listing fine. But when you click on a acuall post you get a blank screen. I turned on debugging but did not see any message.

I searched though 'cbb blank page' but only came up with admin blank pages, not topic, and thats not my issue. Thanks!
