Hi, I'm having an issue with my Xenforo board I just migrated over from myBB 1.6. Absolutely loving the software, but I'm just having one niggling issue. I have a PM from a user, which I need to reply to, but I can't. It isn't because it's locked or anything, the reply box and button are still there. When I click reply, the box greys out as if it's trying, then just goes back to how it was, with my message still in the reply box. Any ideas? All other PMs seem to be fine.
