When I try to restart Apache (/etc/init.d/apache2 restart) I get the following error message:
Forcing reload of web server (apache2)...httpd (pid 26315) not running
(98) Address already in use: make_sock: could not bind to address [::]:81
(98) Address already in use: make_sock: could not bind to address 0.0.0.0:81
no listening sockets available, shuting down
Unable to open logs
Anyone knows what is missing?
