Unable to restart apache2 on Ubuntu 8.04LTS and Plesk 10.x?

Error Message

/etc/init.d/apache2 restart
* Restarting web server apache2 (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

Removed Horde

./usr/local/psa/admin/bin/webmailmng --remove --name=horde

Tried Plesk Reconfigure All

./usr/local/psa/admin/httpdmng --reconfigure-all

but apache2 wouldn’t restart error, “Can not restart web server:”

Finally, Plesk “Reconfigure Server” worked!

./usr/local/psa/admin/httpdmng --reconfigure-server

Not sure if removing Horde was necessary. Anyhow, I’m back in action and Apache2 can be restarted whenever I need!

***NOT WORKING***

killall apache2
