After updates our Civi installation (which is within WordPress in case it matters) often switched all buttons to numbers instead of their labels.
I presume this might have something to do with translation or templating? It tends to go away when I do all the usual post-upgrade things like clearing caches etc, but no amount of fiddling is fixing them this time.
Can anyone suggest what could be related? What can I try? What might cause this?
It's happening to all Civi buttons on the frontend and the backend, but not any non-Civi buttons.
