Add On Help Needed

I tried to update some add-ons and I screwed everything up because I have no clue what I’m doing.

I had an add on that would tell me if my main toon knew the recipe or writ already. If I was on alt, it would still show my main toon knowledge so that I knew if I could sell or keep plan, recipe, etc. I think it’s LibCharacterKnowledge.

My problem is I can’t remember what settings I had in order to see what my main knew. I’ve tried everything. Not sure if it’s broken add-on now or my stupidity. Could someone tell me what I should have the settings on? All I care about is if my main knows.
