Thanks for all your help esmi, I shall try their forum.
I didn’t have photon activated (I don’t think) before I deactivated/reactivated the jetpack plugin, but now that I do have it on, it doesn’t seem to make a difference -it’s still broken.
thanks though!
So it turns out Jetpack is breaking the vimeo embed.
any ideas why?
Will this not break other things on my site?
