How to remove all errors (hopefully)
 

I don't know if I'm too late with this information but hopefully I help someone. If you're getting too many errors you need to update 13 addons and maybe update 3 more. You just need to insert the new versions into the Interface->AddOns folder, overwriting your current addons. If that doesn't work, download a fresh RealUI, install it, then replace the addons.

I recommend backing up your current addons. Keep your new versions just in case you make a mistake. If you actually manage to update all of this with no problems, back that up because it really is a PITA to install.

Update these to 7.1.0; all addons listed ARE updated to 7.1.0

• Aurora
• BadBoy
• BadBoy_CCleaner
• BadBoy_Guilded
• Bartender4
• !BugGrabber
• Clique
• Kui Nameplates
• Masque
• Mik's Scrolling Battle Text
• PhanxChat
• Raven
• Skada

These are currently still at version 7.0.3 and may need updating but probably not

• Bugger
• Foglight
• Grid2

Do NOT update these (stated on the RealUI download page

• cargBags_Nivaya: RealUI
• EasyMail 3.6
• FreebTip
• FreebTipiLvl
• FreebtipSpec

Updating so many addons at the same time is messy. After I updated all of these, I have no errors.

Edit: Spoke too soon. I have only one error and that is nibRealUI_Config: Options initialization failed. Everything else works at least...
Edit2: If you get the above error, try the fix posted by the post after mine!

I jumped the gun, copy the attached file into your nibRealUI_Config folder.

The fix, whatever it was, works. 0 errors for realsies.
