Community Group Broken

Hi!

I am having a problem with a Social Network site on Kentico 7.0.35.

The social network has many groups and one of those suddenly stopped working and is no longer accessible. I can see the group from the back-end, I can manage it and everything seems fine, it's the front-end layout what seems to be broken. If I access the group page using the Content manager (CMS Desk) I can see everything is empty. When I switch to the "Design" tab everything remains empty. If I uncheck the "Display web part content" check-box I can see all the web-parts and it seems correct (no data of course). So I imagine a web-part is failing, or it's failing to load some content and making the entire group page inaccessible, but how can I check which component is actually causing the issue? If I delete the web-parts I would lose the content, so I'm guessing that's not an option.

All settings for this group seem to be the same as those from other groups that are working fine (ie: inherited templates, master pages, etc).

Any guidance as to what can I try? I don't usually use the CMS Desk really and the designer is out for several days, so any help would be much appreciated.

Thanks! Christian
