It is probably related to one of the scripts I’m running.
I have the same problem. Many bugs in Memrise
haven`t seen this in a while (but yes, I used to see this, and have reported it before)
Yeah, this happened to me a couple times now. It seems like for some words there is no audio at all (even when they are shown it doesn`t have any audio whatsoever). In the first few times I was able to click on it at least but now it is impossible to progress without turning off the audio questions.
Hopefully they find a quick solution.
