IMPORTANT MESSAGE ABOUT WP RETINA 2X

In order to comply with WordPress.org, BIG CHANGES in the code and how the plugin was sold were to be made. The plugin needs requires to be purchased and updated through the new Meow Apps Store. This store is also more robust (keys, websites management, invoices, etc). Now, since WordPress.org only accepts free plugins on its repository, this is the one currently installed. Therefore, you need to take an action. Please click here to know more about your license and to learn what to do: License .
