Bug Can't Jion Guild

Dear all,

Do you know why I got bug that I can't join any guild. I just change function from horde to alliance and some people try to invite me to their guild but nothing happen when they invite me. It didn't appear button accept or cancel. Please help to check it our. Thanks

Sincerely

See if you have enabled 'Block guild invites'... i think its in the interface menu.. you will find it

yes i think is because you forgot to leave your guild while you horde and faction changed with it to the alliance side...happened to me few times time ago.
