That command will kill the process that is using port 80. You just need to restart your webserver. For instance, if you are using Apache run:
sudo service apache2 start
Sorry, newbie here. I used webuzo to handle the control panel, I thought it is using nginx, nginx and php-fpm has started but the website still not accesible. I tried starting up apache or apache2 but there are no process with that name. Currently using Ubuntu
Thanks.
If it's using Nginx, then the command would be:
sudo service nginx start
