The fix that can be downloaded makes the add-on load and you can set options. One of the modules showing the player level in the chat doesn't load but doesn't specifically produce an LUA error.

If you can tell me which module it is please, then I'll have a look to see if I can fix it.

Its the player level option in the player name. Doesn't display and also getting some LUA errors with Aceconfig and petbattles

Player level display is proving problematic to fix at the moment, and not sure what going on with AceConfig and Pet Battles, as I updated AceConfig to latest available version.
