Support » Plugin: Event Tickets » Error when emailing attendee list for RSVP event

  • Resolved robdee


    When forwarding the list of RSVPs for an event to an admin we get the following error message. The email does in fact get delivered despite the error message, but we thought we should draw it to your attention.The event is not a recurring event.

    The error message is:

    Warning: call_user_func_array() expects parameter 1 to be a valid callback, class ‘admin_page_tickets-attendees’ not found in /home/coatescentre/BTB1O61A/htdocs/wp-includes/class-wp-hook.php on line 286

    Warning: array_map(): Argument #2 should be an array in /home/coatescentre/BTB1O61A/htdocs/wp-content/plugins/event-tickets/src/Tribe/Attendees.php on line 469

    Warning: array_diff_key(): Argument #1 is not an array in /home/coatescentre/BTB1O61A/htdocs/wp-content/plugins/event-tickets/src/Tribe/Attendees.php on line 482

    Hi. Sorry for the delayed reply here.

    I’ve confirmed the bug when clicking the Export button. Sorry about this bug. I’ve logged it internally and this thread should receive an update once the fix is released (if it doesn’t get auto-closed before then).

    You can keep up with our updates at or just watch Event Tickets’ changelog.

    Thank you.

    Reaching out to let you know we released a hotfix for Event Tickets that addresses the issue with the attendees CSV export. We appreciate the patience while we worked a fix out.

    Please update Events Tickets to version and let us know if the fix works for your site. This fix should solve the problem for Event Tickets Plus users as well (no update required to this plugin).
