Redirect after updating the reservation

[SirRahikkala]

For some reason if I update any data on reservervation, the popup which confirms that update is successful redirects me to homepage, which is not even set anywhere in the settings to my knowledge. So if the url is https://www.domain.com/booking/Web/reservation.php and after hitting ok to popup, it just goes to https://www.domain.com, not to the dashboard.
