I am quite new to this but I edited and updated a website which has the blog area on the homepage. The website is a one page website and the blog area is also called 'News'. The blog was yet still created as a new page and the featured images were shown before using 'post grid' but stopped showing and now shows blue boxes from the branding of the website. The blog page also has been categorized as 'Digital Advertising'. Does anyone have an easy fix to help me get the featured images to be displayed like it used to?
