I fixed my alliance gate about a week ago, so it's at level 1, but can't join an alliance. I've been through all of the groups and there is no join button visible even for those with less than 50 members. Can you help me out please?

Oh, and I've double checked that they have less than 50 members by scrolling down to the bottom of the members list. Just letting you know that as I've seen that advice before about this problem.
