Can't enable MPM Worker on Plesk 12

[Imad S]

Hey,

I've followed this: http://kb.odin.com/en/113007 but my server still say's that it's using prefork

/usr/sbin/httpd -l | egrep "prefork|worker"

 ~]# /usr/sbin/httpd -l | egrep "prefork|worker"
  prefork.c

httpd -V

~]# httpd -V

Any ideas?

P.S. yes I restarted Apache afterwards

It's ok because you have httpd.worker running instead of httpd:

# /etc/init.d/httpd status
httpd.worker (pid 2595) is running...

# /usr/sbin/httpd.worker -l | egrep "prefork|worker"
worker.c
