Have a client cancel a booking

Now I’ve managed by uncommenting 3 conditions to show the link:

<?php
$cancel_link = '';
/*  if( !in_array($EM_Booking->booking_status, array(2,3)) &&  get_option('dbem_bookings_user_cancellation') && $EM_Event->get_bookings()->has_open_time() ){ */ 
$cancel_url = em_add_get_params($_SERVER['REQUEST_URI'], array('action'=>'booking_cancel', 'booking_id'=>$EM_Booking->booking_id, '_wpnonce'=>$nonce));
$cancel_link = '<a class="em-bookings-cancel" href="'.$cancel_url.'" onclick="if( !confirm(EM.booking_warning_cancel) ){ return false; }">'.__('Cancel','events-manager').'</a>';
/* }  */
echo apply_filters('em_my_bookings_booking_actions', $cancel_link, $EM_Booking);
?>

, but now when I click cancel, I get a warning message “You must be logged in to cancel your booking.”, see screenshot:

but my test user is logged in as subscriber… which has permission “manage_bookings”. With this the test user also doesn’t see his bookings in the backend… If the test user has “manage_others_bookings” he can see everyones bookings in the backend and he can cancel bookings in the frontend… What is now the problem here? Permission wrong?

Thanks for any advice,
Chris

Just managed to show the cancelation link with only uncommenting:

/* && $EM_Event->get_bookings()->has_open_time() */

But still no luck with cancelling as subscriber…

OK, it works now, after activating an deactivating some booking and the cancelling options, subscribers can cancel, great! Thanks!
