Sorry to hear you are having trouble. A common problem people have is that they will try to install the zip file directly downloaded from CodeCanyon.net. This usually happens because people are accustomed to installing zip files dowloaded from WordPress.org – which can be directly installed. However, the zip file from CodeCanyon.net includes the plugin install zip, documentation, example templates, example snippets, and more.
Please make sure to install the intense.zip file found within the downloaded file. If you are still having issues, we may need access to your site to figure out the problem.
