Item-Upgrades.lua error

[Grizz2202]

I keep getting the error below on multiple toons. It happens usually when I'm applying something to my weapons like poison or sharpening stones, but sometimes when I'm just hovering quest items.

If I turn Zygor off, it stops completely. If not, I end up getting hundreds and hundreds of these throughout the day:

If you disable all other addons do you still get this error?

[Grizz2202]

Yes, I still get the error.

Try this for a test.

1. Exit the game
2. Go to your WoW/_classic_/Cache folder and delete everything in there
3. Go to your WoW/_classic_ folder and rename the Interface and WTF folders to Interface.Old and WTF.Old
4. Run the Zygor desktop client, click check for updates at the top, and then click on the Install button
5. Go in game to test and then let me know if that fixed it

This will make your game act like a fresh install and you will only have Zygor installed. See if you still get the error like this. You will be able to get your other addons and settings back after testing with renaming those folders back if the test still is the same.
