Maybe I need to restart the site :
How can I do that please ?


If you need to restart website, you can start from IIS or hosting provider admin portal.

You can also restart from admin area. Login with admin credentials and click on gear icon - top right side => Restart Application



Another way is to edit web.config file but put a new blank line or white space. This will restart your web site.
