I have your post grid layout plugin. I have several other categories that I set up previously. I just added a new category and the featured image is not showing up in the grid. I can't find skins & layouts anywhere in my settings. I even tried to make a copy of a different grid and change the category, but the image still does not come up. Can you please advise?
Welcome to our forum.
Please go to Layouts Library and import some layouts first.
Then under the post grid edit layouts tab you will see the imported layouts
Could you please send me a temp admin access to your site, I will check the issue.
