Hey there Natalie!
Thanks for reaching out — sorry to hear that you are experiencing difficulties.
If you are adding the mini calendar via shortcode, you can try the following snippet in your functions.php file →
/*
* The Events Calendar - Change event count to show in mini calendar when used via shortcode
*/
add_action( 'wp_ajax_tribe-mini-cal-day', 'tribe_mini_cal_change_count' );
add_action( 'wp_ajax_nopriv_tribe-mini-cal-day', 'tribe_mini_cal_change_count' );
function tribe_mini_cal_change_count (){
if ( isset( $_POST['count'] ) ) $_POST['count'] = 10;
}
If you are adding via widget, you can easily customize the number of events within the widget settings.
Hope that helps!
