I am unable to track quests or anything that would pop up on the Objective Tracker Frame. I am assuming it is a conflict with ElvUI and I have disabled all that I can via ElvUI options but the errors still proceed. Is there a way to fix? How would I go about disabling your tracker to perhaps fix this? This is the error I am receiving.

Edit: Downloading a quest tracker seems to fix the problem of not being able to track quests and everything else related to that frame. However, the error below still exists and I am still being spammed about it.

in a nutshell, don't use ElvUI with FreeUI, there will be huge conflict.
in your case, you may delete this file FreeUI\scripts\blizzard\objectivetracker.lua, then ElvUI's objectivetracker should work normally, but I guess there will be more error in other parts.
I will add a config panel for FreeUI later 😆
