Hello, i checked the featured image option, it showed empty thumbnails, i unchecked the other options and kept the featured image, it didnt show any result.
although on other plugins the featured image appears.
Welcome to our forum.
Have you used any 3rd party plugin to customize featured image ?
You can also add thumbnail via layout editor.
if possible please send me a dummy admin access so i can check the issue.
kindly note that am using the menu option to view the items
