Probably the same issue as documented on this topic (it’s closed so I can’t reply to it, and I’m a new user so can’t link to it lol): " “Internal Server Error” (when adding new users, aliases, etc.)" id 11454
When I added a new user, the server responds to the request with a 500 error:
POST https://box.REDACTED.com/admin/mail/users/add
email=blah%40REDACTED.com&password=REDACTED&privileges=
responds with:
<!doctype html>
<html lang=en>
<title>500 Internal Server Error</title>
<h1>Internal Server Error</h1>
<p>The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.</p>
The user looks like it was created however.
Looking in the nginx error log, nothing. also checked journalctl -u mailinabox , nothing there either. This is a fresh install.
