I wanted to get an email-notification, when someone makes a new booking. I added these 3 lines from the systemdefaults-file in the config-file and modified them there:
$mail_settings['admin_on_bookings'] = TRUE;
$mail_settings['details'] = TRUE;
$mail_settings['recipients'] = 'email@example.com';
unfortunately the booking-page crashed when I did this and even after I commented the lines out, it did not return back to normal.
This is what I see now: booking.terapeuternevedriget.dk
What could have happened? And how do I make it work again?
