I’ve seen this too today. Has discourse been updated recently?
Having the same issue
I changed the Topic Headline. After that I could not “resolve” the thread.
I get that same error message, although I still seem to be able to mark things as solved.
It seems to be like that but if you return to the topic overview it is not marked as solved any more
Looks like they’ve recently updated to the latest version. I imagine that may be something to do with it.
Yeah, probably a boooogggie in Discourse… Waiting for the next update
