I hope this is the right tech support comm for general Lemmy issues; not sure if this is limited to just Lemmy.World nor do I know if my problem is instance related…
Anyway… Got a DM from a user about an hour ago, but when I try to reply I am given an error that the user does not exist. Their profile is viewable. They just messaged me. I know they are active on the site, as I see them posting pretty regularly… Not sure why I can’t DM them back tho.
The other user is on infosec.pub, and they have an instance specific support community, ask it there, maybe their admin can see something we can’t: !infosecpub@infosec.pub
You instance has a similar general community with similar questions: !meta@pawb.social worth a try crossposting there.
