Listings per page default pagination count

You can alter the number of listings displayed on your listing archive pages or search results by adjusting your WordPress Reading settings.

Visit Dashboard > Settings > Reading

This controls the default pagination for your shortcodes, search results and archive pages. Shortcodes have a limit option to adjust that number of a per shortcode basis. The setting above controls your overall default count.

You can also use hooks and filters to alter this with pre_get_posts.

NOTE: All the shortcodes are default limit of 10, so when using shortcodes set the limit option. EG [listing limit=22]

Divi options override the WordPress defaults

The Divi theme has its own way of changing these values. In your site admin goto Divi > Theme Options and scroll down till you see the Number of ... pages options.

Adjust the Number of Posts displayed on Archive pages option.
