Hi Lewis, I still dont get it :/

Be careful when modifying the site_url setting. Please read all of the documentation that was posted by Lewis. You can severely mess things up if you don’t take it step by step.

Moving your site is a little longer to type then just saying “Do this”. I recommend you have a full understanding of what is needed and what you will have to do to achieve what you are looking for.
