Hey.
WonderfulWhims is tested safe, if something is causing issues, it must be another mod/CC that's problematic in combination with WoW.
What you can do to test it is take out everything from your mods folder for a moment (I know it's probably not what you want to hear) and leave only WonderfulWhims, test it then. If it works (and it probably will) you'll have to narrow down what is causing the issue, 50/50 method will surely come in handy then!
