Lua error every time I log onto any of my characters

[ShadedAxel]

For whatever reason this auction tools and whatever gold.xml is have been giving me non stop errors for the past several days. Every time I log in I'm greeted with the attached error. Doesn't matter what character.

Try doing a full guide reset.

1. exit WoW
2. go to the WoW/_classic_/Interface/Addons folder and delete the ZygorGuidesViewerClassic folder
3. go to the WoW/_classic_/WTF/Account/<your account name here>/SavedVariables folder and delete the Zygor files in there
4. run the desktop client and install a fresh copy of the guides
5. go back in game to test and let me know if that fixed it
