JomSocial homepage not working, profile page is OK

Have installed Joomla 1.7 with the laste Musicity template.
Also installed JomSocial 2.2.4 with the Musicity template.

I have created 2 menu items:

1. Community (must go to the commuity homepage). Menu-item type: 'home' from the community section)

2. My profile (goes to your own profile).

Item 1 - the Community homepage is NOT working. I get a blank page.
Item 2 is working.
Also made some other menu-items to various Community parts and they are working.

Only the function Home from Community is not working.

What's up? Can anybody help me?
