Unity Post Scroller widget has been developed in such a way that it does not display anything if the post list to be displayed in the widget has not been selected. To check it, you can do the following:
- Make sure that you have correctly selected the post type to be displayed in the widget settings. You may have marked the wrong post type, not the one that is currently set in the widget.
- If the post type has been selected correctly, make sure that you have selected the necessary posts to be displayed. You may have not selected any posts.
