"LUA Warning" window keeps appearing after using /reload (Not using add-ons)

I typed /reload. I still don’t remember why I did it, I didn’t have a good reason to do it. But as soon as I reloaded the UI, I’ve been getting a “LUA Warning” message that’s filled with information I don’t understand. There’s a lot of: “NewPlayerExperience” and “Blizzard_Tutorial” mentioned in the message, and it keeps popping up.

I don’t use add-ons, and I also tried the Scan & Repair tool in the Battle.Net App, but it didn’t fix it. Anyone know why this has happened?

It took a while, but it seems like this resolved it. Thank you.

EDIT: I tried renaming all of the folders, but apparently this “LUA Error” window is back again. It’s really annoying that you can’t just tell it to stop notifying you. So, is the last option to uninstall and reinstall WoW?

You can tell it to stop by typing in this command on the chat line:
/console scriptErrors 0

You must have enabled scriptErrors at some past point with /console scriptErrors 1
Turning it off doesn’t mean the errors go away, they are just being hidden. The functionality that’s broken will still remain broken. You can perform the below steps

But if they don’t work post in the Technical Support forum
