Open the file iView.lua with a texteditor and search for this line (line 267):
Code:
if not SWF:IsAddonVersionSameGameVersion(API[1], API[2], ADDON_NAME) then return end
Change it to a commented line by adding the prefix --
Code:
--if not SWF:IsAddonVersionSameGameVersion(API[1], API[2], ADDON_NAME) then return end
Save the file, do a /reloadui ingame and try if it works then.
You can also change the ## ApiVersion: xxxxxx inside the iView.txt file to
##ApiVersion: 100025 100026
This will make the addon stop saying it's outdated.
