Turns out the addon I uploaded doesn't work on any client but my own. Don't you love when that happens? Anyway, I've got a bit of a problem.
I was trying to find out why my addon was failing so I copied over a fresh installation of WoW and dropped my addon in along with BugGrabber and so on.
As soon as I logged in and tried to open my addon, I get this message:
Mind you, it isn't an error. BugGrabber can't catch it. That's just all it says. Googling it doesn't give me any results. Does anyone know why this would be happening?
