I keep getting this error when I try to access the home page of a Facebook group. I'm a member and see the posts in my timeline. When I try to go to the group page, it shows this error. It's been happening for several days now. I've reported it to Facebook also a few days ago and it's still broken. When I clear my cookies, I can see the group, but when I log in, it still shows broken.
This happens for two groups, one public, one private. All the other groups work fine.
How can I access these two group's home pages?
