Unable To View Website As Designed

I have been working with the Di blog theme (free version) for several days and cannot see any of the changes I’ve made. The website is not appearing as I configured/designed it using the “customize” option. If I visit the website as a visitor and not an administrator (which I am) the functions I created in the theme customizer are not showing up. What am I doing wrong? Thank You! Dr. K. Jesse Roig
