Apache won't start after successful upgrade to 4.2.23

Hi !

My apache server won't start since i successfully upgraded from 4.2.22 to 4.2.23...
I have a socket error can anyone help me please, i have no more access to frontend, to backups, to plexmedia server...

Here is the commande line i'm trying to use to start apache

apache-ssl -f /etc/frontview/apache/httpd.conf -k start

and here is the error i get

apache-ssl: Could not reliably determine the server's fully qualified domain name, using 192.168.2.200 for ServerName
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs

Any help would be welcome !
Thanks a lot
