With 1.5.1, I get this when I try to call RegisterStyle():
Code:
[19:39:13] Interface\AddOns\oUF_Nivaya\oUF_Nivaya.lua:897: attempt to index global 'oUF' (a nil value)
Looks like it's not being loaded, but I don't get any specific error messages before that one.
**edit: Ok, got it. It was that XML error.
