Running Questie-v6.3.16-TBC.zip

was working fine and for with no trigger when I logged in I got this error message:

[ERROR] Error during initialization!
Interface\AddOns\Questie\Modules\QuestieMenu.lua:590: bad argument
#1 to 'band' (number expected, got nil)

I've tried reinstalling, disabling all other addons, i've installed from both curseforge and direct, I've installed manually,

Help :(

You should remove the Questie.lua files you can find in your WTF folder. Looks like something got corrupted when you updated.

I have a similar issue with initialization after I updated to 6.3.16 "error during initialization, ...Addons/Questie/Modules/QuestieProfessions.lua:17 bad argument #1 to 'pairs'(table expected, got nil)

I deleted all the Questie.lua files ...

@alin-faur If you have deleted all Questie.lua and Questie.lua.bak files in your WTF folder Questie should startup just fine. Make sure to delete the correct files in the correct folder.

If you can't manage to fix it hit us up on Discord.
