Popnui error

[Gaibban]

I deleted Frame xml, deleted interface folder and installed the Alpha build. Upon login i got the following::

String: Interface\AddOns\PopNUI\PopNUI.lua
Line: 501
Count: infinite
Error: attempt to perform arithmetic on global `SHAPESHIFTBAR_YPOS' (a nil value)

at the character select screen, click on the AddOn button then uncheck PopNUI this will fix the error you're getting.
