SOGO webpage error

IMO the problem is due to a recent update of nethserver-httpd or virtualhost in the beta2 release.

I guess so.
You could try with this (not tested):

rm -f /etc/httpd/conf.d/SOGo.conf
yum reinstall sogo
systemctl restart httpd

Does anybody think about alternative? Horde for example?

Try webtop 4
