CT Barmod generating LUA error with restricted frames

[kinghq1]

This has been happening for some time, months. so I cannot say when xPack caused it. We all know how well Blizzard loves to break addons. Out of all my addons, CT Mod is the one I have used for years. Please fix :-(

So I disabled CT_Barmod and then got this one:

yeah, more CT errors. Based on it being 10 months without an update, I think us CT Mod users are SOL . . .

[BloodyFess]

I found temporary fix for "MainMenuBar" errors! What we need to do:

Addon has 3 files:
...AddOns/CT_BarMod/CT_BarMod_Groups.lua
...AddOns/CT_BarMod/CT_BarMod_Options.lua
...AddOns/CT_Core/CT_Core_Other.lua

In every file need to find ALL STRINGS contained MainMenuBar and replace they with MainActionBar. Errors has gone...

[kinghq1]

You are awesome, thank you for this. I made the changes and no CT_Mod errors.
