I emailed the theme developer and they sent me this:
Yes, if you're using blog posts on the homepage then the blog posts are loaded from a custom query from the blog block in the page builder. By far the easiest way for you to get this working is to modify the query in the blog block;
If you forward that info to the plugin developer, he will be able to tell you what to add to include the events.
In that file the query looks like this;
$paged = (get_query_var('page')) ? get_query_var('page') : 1;
$blog_query = new WP_Query('post_type=post&paged=' . $paged);
if( $blog_query->have_posts() ) : while( $blog_query->have_posts() ) : $blog_query->the_post();
Forward this info and you should have an answer from the other developer :)
I'm closing this ticket now as the main question is moving towards 3rd party plugins, which is not covered in these support tickets.
So... can you help me?
