Guild Wars 2 Forum - Bugs: Game, Forum, Website

So I wanted to invite a guy in my guild, but it says that I am full of memberships. (see atachment)

The strange thing is I can invite other people , except this guy.

I hope you guys can help me.
Thanks!

Maybe he has to much open invites. Usually problems with invitations have to do with that.

BTW there is a special guild sticky for guild problems.
