Edit: I just force installed the latest Authentic Theme and it appears to be working properly now.
I recently noticed that on almost all accounts users are unable to see their email messages. If they change their Themes to something else the messages load. Using Authentic Theme the red bar just moves back and forth as it attemps to load the messages. One account I know of still appears to work with Authentic but I am not sure why. I have restarted Usermin but since it works with the other themes I figure it mut be theme specific.
Has anyone else seen this behaviour.
My system info is:
Webmin version 1.910
Usermin version 1.752
Virtualmin version 6.06
Authentic theme version 19.33
Operating system CentOS Linux 7.6.1810
Perl version 5.016003
Path to Perl /usr/bin/perl
BIND version 9.9
Postfix version 2.10.1
Mail injection command /usr/lib/sendmail -t
Apache version 2.4.6
PHP versions 5.4.16
Webalizer version 2.23-08
Logrotate version 3.8.6
MySQL version 5.5.60-MariaDB
ProFTPD version 1.35
SpamAssassin version 3.4.0
ClamAV version 0.101.2
Did you do that from Webmin? I might try the same thing as you suggest in your edit, as Usermin is working with the old themes..
if you go into Webmin>Usermin Configuration>Usermin Themes
and set the usermin theme to anything but authentic, usermin works no problems (including emails can now be sent). It has to be some kind of glitch with the Authentic theme i think?
EDIT...
Oh shit...I cant do that, I already have the latest theme (19.33). My only option would be to go back to an earlier version.

Please note the solution to this problem is as follows...
Do not use the Authentic Theme as the Usermin default for new user accounts!!!
IF after creating any user account this bug appears, go into either Webmin/Virtualmin/Usermin and change the theme to any other theme other than Authentic. Refresh your web browser (or sometimes a relogin may be necessary)
Usermin should now function if one goes back to the authentic theme mostly ok. There is a caveat, if one first selects dashboard, then attempts to click on the "compose" button...it does not work reliably. However, if one selects Usermin>Inbox menu, then selects compose new message, it works.
PLEASE PLEASE PLEASE someone at virtualmin provide a fix for this!!! I am concerned that the silence from Virtualmin developers is because they actually cannot figure out a solution to this issue?
I am offering to provide full access to my server "as is, warts and all" so that Virtualmin guys can problem solve based on my setup (which may have mistakes that are contributing to the problem?)
