The picture that thetravellor posted is exactly what I was talking about, I can accept invites and give out invites without OQ or anything. This is directly an Oqueue problem I believe. :/
I'm having the same problem that I posted on here yesterday but only got 1 response that didn't help. I have disabled all other addons re-downloaded OQ. Even re-downloaded WoW yet it is still auto-declining invites.
I do have 1.8.0 and disabled all other addons. Only about 1 out of 20 people it accepts the invite. I'm not the only one with this problem. It was working last night before the server merge.
