Tried the nUI.lua file in the other thread but it did not clear this error. Is this one coming from nUI or !BugGrabber?
2010x [ADDON_ACTION_FORBIDDEN] AddOn "nUI" tried to call the protected function "IsDisabledByParentalControls()".
!BugGrabber-r198-release\BugGrabber.lua:552: in function <!BugGrabber\BugGrabber.lua:552>
<in C code>
FrameXML\MainMenuBarMicroButtons.lua:229: in function "UpdateMicroButtons"
