Hey @Bobbby,
Thanks for reaching out. You can alter the number of “related events” shown by adding a snippet like this to your theme’s functions.php file:
add_filter( 'tribe_related_posts_args', 'tribe_change_number_of_related_events' );
function tribe_change_number_of_related_events( $args ) {
$args['posts_per_page'] = 4; // Change this to whatever number you'd like.
return $args;
}
☝️ Now, please note that this code will only change the number of events shown. The design handles only three by default, so you may need to write custom CSS and such to make your design handle displaying four events well (or whatever other amount).
We cannot help with custom coding, so for design refinement after you make this change you will have to take the reins on that. To make writing custom CSS on your site easier, if need be, definitely check out a [free!] tool like Firebug if you use FireFox, or the Developer Tools for either Safari or Chrome. They have “Inspector” tools that let you zoom right over the element whose styles you want to adjust, so that you can more easily adjust them to make things look sharp.
I hope this all helps!
Cheers,
George
