going to http://www.mydomain/pcbb/bb-admin/themes.php just puts me straight back to the home page (my bbpress installation is actually in a directory called pcbb)

Just to make sure I have done everything correctly

I have created my-templates in pcbb

This is not integrated with any wordpress tables – they are all standalone – the bbpress database has the 8 bb_ tables in it and nothing else.

Copied the theme in its own directory to my-templates

I never have seen a presentation menu even on the new install which was 0.8.1. The new install didn’t have bb_ as table prefixes, although I have since corrected that (after upgrading to 0.8.2
