Yes, that helped, thanks.
"httpdmng --reconfigure-all"
However, first time I executed that command it failed - complained about invalid conf files:
"/var/www./vhosts/mydomain.com/conf/vhosts.conf~"
That's a backup copy of my vhosts.conf.
So I removed the file "vhosts.conf~" on both my domains.
And then executed again "httpdmng --reconfigure-all". It worked.
After I restarted web server, etc, my web is OK.
