Function "wipe" doesnt exist in 2.4.3 by default. So you'll have to create it yourself
Create Addon, let's call it !Compat
! is for loading it among first addons.
Create folder Interface\AddOns\!Compat
Create file in that folder named !Compat.toc with contents:
##Interface: 20400
##Title: Compat
main.lua
Next we create main.lua file in the addon folder. Contents for this would be
local pairs = pairs
function wipe(t)
for k,v in pairs(t) do
t[k] = nil
end
return t
end
And you are done. Alternatively you copy paste the function into addon and hope it is loaded before it is used. There are addons made by developers to make 3.3.5a addons compatible with tbc so I'd recommend finding one of those.
