Webmin version is 1.900
Virtualmin version is 6.05
Usermin version is 1.751
Nothing visible happens when I click the "New message" button in Usermin. Not even a loading bar.
I have tried both with a domain user (email@example.com) and also as the root user. I have tried both with Google Chrome and Mozilla Firefox.
EDIT: I have made a mistake in the forum I entered to. Please move this to the Usermin forum. I would do it myself if I could. I'm sorry
