Our regular non-admin/non-mod users are unable to add other users to a personal message. I’ve impersonated, changed themes, poked through settings… in none of the cases will clicking the “Add or Remove …” button at the top of a PM thread do anything at all when impersonating.

Hey, all. We started experiencing issues with this after an update a few weeks ago. Users can remove other participants in a PM they own but are no longer able to add any users: [image] The invite permissions are set to anyone with TL2 (which my test user has) and “enable personal messages” is t…

I am also seeing this behavior with latest commits :cry:

Can we repro any problems here @tshenry ?

[image] sdpiowa: Users can remove other participants in a PM they own but are no longer able to add any users: I got around to digging into this a little today, but am unable to reproduce the mentioned behavior. I attempted three messaging scenarios using the settings mention (PMs enabled and…
