 * Hello.
 * The issue that you experienced is because you updated the Booking Calendar Free
   version to update 11.4 but you still was used the old version of Pro version 
   of Booking Calendar 10.14.6
 * To resolve this issue, please wait for the update of Booking Calendar Free version
   11.4.1, that will come in next 18 hours or you can request the latest update 
   of your Booking Calendar Pro version 11.4
 * Kind Regards.
