I just upgraded my site to 2.9.0beta2 (dfc19c62f8) via ssh (by pulling and then rebuilding via launcher). Everything seems to be working fine, except that all polls seem to have had their votes reset, and the poll builder is no longer available when composing a post.
I have confirmed that this persists even in safe mode, so I suspect that I broke something by accident. Is there some way to debug what might be going wrong/how to repair this? It’s alright if the poll votes data is lost, although I would obviously prefer if that could be avoided!
