This is the first time I am even trying as this is quite a new mailcow instance. (not yet used productively)
I have recently created a new inbox with no-reply@… and lost the password so I went back, entered a new password twice, clicked save and still couldn’t log in.
So I had a closer look and it seems I can’t save the new password nor any changes to inboxes.
This is what the screen looks like before I hit save:
This happens after clicking save>
P.S. This thread might be related as I noticed I have some bugs on my mailcow UI interface: https://community.mailcow.email/d/694-possible-display-bug-in-mailcow-interface
