 * Testing the free version before deciding on whether or not to purchase the Pro
   version. Upon installation/activation on a fresh WP site (v.4.2.3 with default
   Twenty Fifteen theme) the following red error message is displayed:
 * _The plugin generated 240 characters of unexpected output during activation. 
   If you notice “headers already sent” messages, problems with syndication feeds
   or other issues, try deactivating or removing this plugin._
