If you want to prevent your customers from publishing website copies on Facebook, you can remove the corresponding option from the editor. This can be done by adding a line to the configuration file.

To make the functionality for publishing sites on Facebook unavailable to users:

1. On the hosting server, open the configuration file /usr/local/sb/config.

2. In the [general] section of the file, add the following line:

   facebook_application_url = ""
   

3. Save the file.
