The pages were constructed earlier with SiteOrigin page builder where the WPDM shortcodes were inserted in SiteOrigin’s text widget. These are working fine.
But when creating new pages with the WPDM shortcode in SiteOrigin page builder, the pages are not displaying any content. After inserting the shortcode in a page/post, when the page/post is updated/saved, the updated page/post is not refreshing. Instead, a blank page is displayed.
Also, the old pages which are otherwise ok, if they are edited and updated, they are not displaying any content either in the front-end or in the back-end.
