We'll create fresh WordPress site with Export Themes installed. You have 20 minutes to test the plugin after that site we'll be deleted.
With this plugin you’ll be able to export your themes in a .zip file and then install with that .zip file the same theme in other servers using the “upload” feature of wordpress.
After installing the plugin, you need to go to the “Export” subsection in the “Appearence” menu. Just select the theme you want and then click in the “Export” button. You will get a .zip file to download. Once you have the .zip file in your computer, you can install the theme going to Appearence/Themes/Install Themes/Upload in your wordpress administration pannel, and then select your .zip file and click on “Install now”.
