Hi and thanks very much for all your help so far.
I have used
<?php echo do_shortcode('[events_list_grouped mode="monthly" orderby="event_start_date" scope="future" category="118" attribute date_format="F Y"]'); ?>
to call a grouped list of events but none display.
On inspection, my categories page shows no events within many categories, even though each event belongs to multiple categories:
Can anyone give me a heads up on what I'm doing wrong?
