How do I order sessions that are occurring at the same time on agenda page?

Please do the below change:

1) Open/wp-content/conferencepro/event-framework/helpers/cpt/sessions.php

2) Around line number 65, you can find:

return “mt1.meta_value ASC, $wpdb->postmeta.meta_value ASC”;

3) Please change this to:

return “mt1.meta_value ASC, $wpdb->postmeta.meta_value ASC, menu_order ASC”;

4) Save the file.

This is a parent theme change. You need to reapply the change when you upgrade the theme.
