This is my website (Super Duper Products) with the latest version of WordPress (3.4.2). I am CURRENTLY using the premium WordPress ThemeForest theme Confidence, which is working perfectly.
However, when I try to change my website's theme to any other theme like Gonzo, Avada, U-Design or Volt, the website does not show up properly and it is only basic simple HTML that is making the template work. I don't want a 90s theme! Here's a screenshot: Wrong Theme Format.
When I changed back to Confidence theme it worked properly but when I switch to another theme, it does not work properly. I don't think that there is an error in uploading the theme files to my WordPress site.
Please help, I think it's something with my website which is conflicting with new themes. The themes are more than awesome with cool features and user interface and I don't think that they have a problem.
Any help would be greatly appreciated. If you need any more reference, please ask.
