ConfigServer Security & Firewall not load in Virtualmin


When i tried to access to the page of ConfigServer Security & Firewall in Virtualmin, the theme reload the page and send me again to the main page of Virtualmin. I cannot access to config page of the firewall.

My system:

CentOS Linux 7.2.1511
Webmin version 1.810
Virtualmin version 5.04
Theme version Authentic Theme 18.10

I think it is a problem with authentic theme. I can access to the firewall in my iPhone with the default mobile theme.

Thanks for your help!


Same issue here. 4 servers (1 physical, 3 vps).

It does seem to be theme related. If I switch to one of the (ancient) other themes it works.
