Calendar not working

Hi,

The appointments calendar has stopped working completely and thus, not appointments can be booked. After selecting the service and the service provider, the customer can’t select any dates in the calendar. Either the calendar prompts to select another date (even though the date would be available for the service) or when selecting the following month there is a loading figure and nothing happens. The calendar was working perfectly yesterday.

Hopefully there is a solution to this problem.

Thanks you!
