Let´s start with the most important things first:
1. [ EDIT: Removed by moderator. Let's stick to support issues on the forums here. Thanks ]
2. The BP BuddyBar (BuddyPress Admin bar) brakes with my install and it lists all the links below the Network admin and the GridMarket theme.
3. Also when I upload a header it doesn´t crop it properly, I tried many times, but it cuts the image in wierd ways: http://linkedbees.com/marketplace (pls see here the buddybar problem and the header problem).
I am using this theme as a subsite in a MU install, does it HAVE to be the main site to support buddypress? I don´t see the community features.
