On the TBC anniversary servers i am now getting a LUA error whenever i click my chat box scroll arrow, i have tried disabling all addons, running the repair tool, using /console cvar_default and doing a full UI reset multiple times, nothing works; any suggestions?

LUA code:

got the same issue, I wont be deleting and resetting my settings if it did not work for you. I usually used prat as a chat addon, which currently is disabled. Waiting for that to be updated.

resetting cvar did it for me. /console cvar_default
