I do not know how to solve this problem:
It happended 2 things and do not know how to check wich one brake virtualmin pro.
1) I have payed for the reneview of virtualmin pro licence that was expired from 4 days.
2) I have updated virtualmin and webmin packages
After that I am unable to access to web interface or throught remote as root
I can only access via ftp (no ssh) only normal mode with a secondary admin user that has not privileges to access to root folders.
I get user and password refused if I try to access as root
now it's a big problem cause I do not know other ways to access to server ...
Some days ago I provided to Virtualmin staff a support access to enter into the server but I am not able to retrieve datas cause the only thing I see is a web page with just
System Information and Logout links ...
Updating Virtualmin or reneview licence brake server
