Unique Post System in ColorMag PRO
Almost a dozen widgets are bundled in the theme ColorMag Pro and ColorNews Pro, which are used to display various posts along with its featured image. These widgets display latest posts or posts from some specific category. So, when many widgets are used in the same page like the HomePage of ColorMag Pro demo site, it is likely that the posts are repeated. That means same posts can be displayed in several places by the different widgets.
Appearance -> Customize -> Additional Options -> Unique Post System
The posts repetition is restricted and a post is displayed only once in the page. However you can always uncheck the option if you don’t want your posts to be unique.
