"Too many linked calendars"

I accidentally added another calendar and then canceled it. But, in addition to being displayed as “Too many linked calendars”, the reservation page also displays that it is out of the holding period. What is the cause?

Hi @momo welcome to the Forum! If you unlink the second calendar, the message should go away. For the the message about the date range, you may need to adjust the fixed start and end date: Set fixed start and end dates for your bookings - YouCanBook.me Support
