Boss Unit Frames disappeared

The boss unit frames disappeared from my game and I can’t figure out how to reset them. I feel like it used to be in interface options - unit frames - but now it’s not there. Retail. Thank you

Grab AdvancedInterfaceOptions it has a CVar Browser you should be able to locate the setting in.

I wasn’t personal aware that the default UI had boss frames, but, if it does, AIO will help you locate the switch.

I want to enable enemy unit frames on my screen like the party frames. I thought it was an option at one time - maybe it was an addon then?

Honestly couldn’t say. I haven’t used the default UI in over a decade.

There’s Arena Enemy Frames or Boss Frames as non-friendly “group” unit frames. Other than that, it’s just nameplates.
