datitisev there is no critical error. It's just "wip" version. Updated automatically with regular routine to update Flarum. Poll for me now looking (pc/mobile/etc):
I am searching a way back for previos stable version. New version have a migration routine, so database maybe altered in some way. Is it possible to roll back? Errors also aquired, e.g. it didnt update page, after adding poll (you need to refresh page manually for poll appearing). I am sure that is just WIP version, published in cause of some error.
Flarum 1.8.5, default theme.
