Directorist plugin and some of the directorist add-ons use different pages with some specific shortcodes to function properly. You need to make sure all the pages are set properly in the settings. The directorist plugin and any directorist add-on should create all the required pages automatically for you and you just need to assign them to the settings if they are not already assigned. However, if the page is not created/you deleted before, then do not worry. You can create those pages manually and put the shortcode inside each page. All required shortcodes and other information are clearly mentioned in the settings page.
Please go to Directorist Listings > Directorist Settings > Pages, Links & Views Page. And make sure the following pages are set properly. You need to assign those pages for charging your users using created plans.
