Hello everybody. 

my hotel suddenly went on closed and not bookable status and when I've emailed support they said its due to my room availability that needs to be updated. I'm trying to update but it shows some technical error and does not allow me to do so. attaching the screenshot below. tried refreshing the page etc but no result. error
