Ok, this sentence means "your weekend went well?"

What is the context?

"ça a été" means "it went well or "this went well" so you can use it versatilely. There is often a hint of the thing could have gone wrong, bad or failed. It always refers to somethnig that has happened in the past. "ça" could refer to anything. Exemples: - after an interview, your friend can ask you : ça a été ? Meaning: did you do well during the interview? If you did well, your answer can also be : oui, ça a été. - after a fisrt day at school, you can ask your child/friend : ça a été ? Meaning: was this first day okay? - after an holiday, you can ask somebody: ça a été tes vacances? Meaning: how was your holiday? The same for your weekend, week, any event. It is of course very spoken French, you will not write it in an essay or in a formal text. J'espère que cette explication a été enrichissante, Cordialement, Carine.

Yes it means " was your week-end OK?" In English however you forgot to put an S to the verbs in the third person singular "the person asks this QUESTION and the other answers that"
