Translation:If you meet with her, do not come to this house again!
In British English we don't say "meet with her". "Meet her" if it's for the first time, or "meet up with her" if it's pre-arranged, as I think is meant here.
Thanks. Yes, I know it is American English. Usually Duolingo tries to accommodate both. I got marked wrong for "meet up with her" but I think it should be included. "Meet up" is mentioned half-way down the article that you linked. I was wrong to say "meet her" is only the first time, but it is not pre-planned, as your article confirms.
