Webmin crashed after virtualmin installation!

I updated virtualmin by installing the new version(3.21) of it over the older(3.201) by using the install mod function in webmin.
As usual. This always worked.
But not this time.

After ‘updating’ virtualmin (basic, not pro), webmin closes its self.
[[root@server ~]]# service webmin start
[[root@server ~]]# service webmin status
Webmin is stopped

How can I repair this?
I do not want to loose any websites in virtualmin.

[[root@server ~]]# /etc/init.d/webmin restart
Stopping Webmin server in /usr/libexec/webmin
/etc/webmin/stop: line 4: kill: (21397) - Unknown proces
[[root@server ~]]# /etc/init.d/webmin status
Webmin is stopped

=> help please


ps aux | grep miniserv
kill -9 1234
