 * When activating this plugin I get the following error message up in the header
   area of the site:
 * Warning: session_start() [function.session-start]: Cannot send session cookie–
   headers already sent by (output started at /home3/daryle27/public_html/farm/wp-
   content/themes/twentyfourteen/header.php:13) in /home3/daryle27/public_html/farm/
   wp-content/plugins/beds24-online-booking/beds24-online-booking.php on line 62
 * Tried it with multiple themes and with all other plugins deactivated but still
   get that error. Hoping for a fix.
 * Thanks

 * We are aware of this and will fix it with the next update. You can manually fix
   it when you click on “Plugins” in your right hand WordPress menu. Go to “Beds24
   Online Booking” and click on edit. This should open the file beds24-online-booking/
   beds24-online-booking.php
 * Scroll down the code until you find this line:
 * session_start();
 * comment it out like this:
 * // session_start();
 * then save.
