Quote from MedalistI was getting the same error, I found out how to make it work again...
1. Open World of Warcraft\Interface\AddOns\Prat-3.0\modules directory
2. Edit CopyChat.lua file in notepad/editplus etc.
3. Goto line 315
local dropdownFrame = _G[UIDROPDOWNMENU_INIT_MENU]
local dropdownFrame = UIDROPDOWNMENU_INIT_MENU
5. Save file
6. /reloadui or restart game
nm its fixed.
