Quote from tenchuCan't seem to access the Blizzard_RaidUI function by right click the raid frame. I used able to right click on the Raid frame and select options, such as setting maintanks for the raid.
I also had this problem. I don't have any other major addons, I only have like Bartender4, quartz and Bagnon right now.
I raided for the first time since the 3.02 patch. I had my X-pearl Raid frames open displaying the entire raid and when I would right click on anyones name in the X-pearl raid frames I would get a LUA error.
The frames display just fine all of their functions were great, but I kept getting that LUA error from right clicking on a players name in the raid frames.
