Why did my group home page change?

Question

The only areas I can access are "Home" and "messages", the rest are in smaller print and all black lettering and not highlighted.

Answer 1

It is an option with the owner.

To hide or show details of members and other things.

Even messages need not be shown to all.

Answer 2

if your a member, the owner disabled those other area's so members cant access them.

if you're the owner- someone within the group has the priviledge to edit group settings and that's why they're seen that way-
