Hi Glenn,
Thanks for reaching out on this and for trying out 3.10 RC!
Indeed, class names had been refactored, so updating the class name to ‘Tribe__Events__iCal’ will get that working again. The code should look like this now:
remove_filter('tribe_events_after_footer', array('Tribe__Events__iCal', 'maybe_add_link'), 10, 1);
Let me know if that works for you,
Have a great Friday,
Nico
