Hi Kiev,
Thanks for your reply.
Did you edit the custom post type to show that box you see in this screenshot?
This isn’t about the template page (the one you’ve linked) but rather the \wp-content\plugins\sportspress-pro\includes\sportspress\includes\class-sp-post-types.php
file, around line 436.
If you haven’t done this edit, please do so, change it from this:
'supports' => array( 'title', 'editor', 'author', 'thumbnail', 'excerpt' ),
To this:
'supports' => array( 'title', 'editor', 'author', 'thumbnail', 'excerpt', 'comments' ),
That should add the comment field to your events. Please notice that you will lose this edit in future plugin updates.
Thanks!
Kind Regards,
-Roch
