I am really sorry that @towhid missed the shortcode part. To view the custom post types in the dashboard page, you need to use a speacial format for each post type. Suppose, you have a custom post type project, so the shortcode to show all the projects in the dashboard will be [wpuf_dashboard post_type="project"].
If you want to show all the custom post types available in your site, then you have to place shortcodes for each post type. I have logged in to your site and found the post types below.
So your shorcodes will be like [wpuf_dashboard post_type="ts_testimonials"], [wpuf_dashboard post_type="sp_event"] and so on.
I understand the situation you have to go through and how annoying it was to wait for some instructions. I apologize for all these things.
As a consolation, I would like to offer you two free add-ons and free priority support for next 1 month. For any other issues or question in future, you can directly mail to firstname.lastname@example.org and I will personally assist you and make sure that those get resolved within 2 working days.
