You dont need addon for HIT since version 1.13.

" DataTexts - Added Hit / Spell HIt / Spell Crit "

Untrack all the quests. Or install addon hidequesttracker: https://www.curseforge.com/wow/addons/hidequesttracker FYI: If you have Questie enabled and HideQuestTracker, please make sure you disable the option in Questie called "Enable the Questie Tracker" if you dont want to see a quest tracker frame.

Yea.. You'd have to do it that long way to be able to do it.. The one I was referencing is gone. UnitSelectionType Ohh, I was not replying to you. I didn't see your post until after I posted mine. I just started working with tags, lua and wow API in general. You make it a lot easier with your code....

I use ClassicThreatMeter with ElvUI and everything is working fine.
Probably another addon is crashing CTM and that is making ElvUI problems?

ClassicThreatMeter version - 1.10-classic
ElvUI version - 1.14

But if you dont need CTM, just leave it disable.

hehe, we all start as noobs!
Glad you worked it out!

please show a print of the configs from unitframes > player > power

Use Elvui StyleFilters.
There is no threat on Classic.
All you can do is by target. If enemy targets you, it glows red or something like that.
