How to restart Apache?
Note: To restart Apache, it is required to have either administrative access to the Plesk interface or root SSH access to the server. If you do not have the menu Tools & Settings in the Plesk interface or root SSH access to the server, please contact your server’s administrator or hosting company support that manages the server.
By default, Apache is reloaded automatically after changing any Hosting Settings in Domains > example.com.
