This plugin is no longer needed. GeoDirectory is now compatible with Enfold out of the box
Automatic installation is the easiest option. To do an automatic install (make sure you already have GeoDirectory and Enfold installed), log in to your WordPress dashboard, navigate to the Plugins menu and click Add New. In the search field type "GeoDirectory - Enfold Compatibility Pack" and click Search Plugins. Once you've found the compatibility plugin you install it by simply clicking Install Now.
The manual installation method involves downloading the plugin and uploading it to your webserver via your favourite FTP application. The WordPress codex will tell you more here.
Automatic updates should seamlessly work. We always suggest you backup up your website before performing any automated update to avoid unforeseen problems.
