WordPress Speed Up Service | WordPress Website Maintenance Packages Reply To: New To WordPress – Theme Preview Not Working?, by sbsee Hi, I am facing similar issue. I have just installed WordPress Version 4.8.3. I have not installed any plugins. The Themes I tried are Twenty Fifteen, Sixteen and Seventeens. When I click Live Preview, it return my old domain page. I checked with my Web hosting provided, they mentioned I need to define a default HomePage. Where can I find this homepage on wordpress? Is it a HTML file? Thanks, SiewBoon Reply To: New To WordPress – Theme Preview Not Working?
