What addons are you running?

Most of them are listed above with the exception of Vuhdo, Rematch, Titan Panel, and Broker_WorldQuest, Silence, and Pawn. I also have several installed but not active - MoveAnything, Bartender4, Weakauras, Personal Loot Helper, Fishing Buddy, and Method Raid Tools.

Turn all of them off and see if the error appears. If it doesn’t turn your addon’s on one by one and /reload after each is enabled until you find the one causing the error.

I’ll try that. I’ll report back with my findings, if any :slight_smile:

Edit: I never was able to see which addon was causing the issue. I decided to wait until after dinner to sit down and disable / enable one by one. When I came back I had several addons that had been updated so I updated those. Error went away.
