Hello Farhad,

Firstly, in Step 5 Export > Upload the Website to Internet make sure that you set your WebSite Address (URL) to begin with https:// as shown in the screenshot below:

The next two steps have nothing to do with WebSite X5, and must be implemented on the server where you host your website.  Your webhost should be able to assist you with these if necessary.

Install an SSL certificate on your server which references the domain name of your website.  Typical instructions can be found here:

Enforce the use of the SSL protocol by implementing a redirect in the .htaccess file on your server, to direct traffic away from the http:// address and re-route it to the https:// address  -  example code here:

Finally, here is a useful article which gives a general overview of the entire process:
