 * I like your plugin, but with the newest version I am receiving this error message
   upon activation:
 * `The plugin generated 325 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.`
 * On the front end I cannot dismiss the message:
 * `Get 30% discount on WooCommerce Product Feed Pro. Use the coupon code BLACKFRIDAY16.`
 * Which is causing the DOCTYPE to be removed from front end of the website and 
   causing issues with other plugins that I’m using.

 * Hi,
 * We have released a new version by removing the promotional message.
