I am brand new to WordPress. I installed it as directed by my host, IPOWER through Simple Scripts; I have accessed the dashboard and installed a new theme, BackMyBook 1.5.3. The theme appears on the dashboard page as a thumbnail along with buttons which allow me to upload my profile photo, etc., but I cannot load the new site to preview the changes I am making. All I have access to is the Dashboard page of WordPress. What have I done wrong?
