Closed bookings

Hi, we are unable to open any bookings in our calenders (we have 3 properties)  from the 2nd of sept 2020 to 2022. It is just saying closed with a red banner (in Monthly view) and will not allow us to to set them as open or available, please help?? 


Change Calendar view to List View.  Then open on left hand side and you can check what is missing.  Are they set to open Open/Closed, rooms available, Rates set. 

You can do a Bulk update to change whatever is wrong.
