My website is http://garylott.lifesbeatenpath.com/
In the past few months I've had some support help - which was great by the way - and the problems were fixed. I had issues with author boxes and social sharing icons showing up all over the page instead of just after a post. Those were here:
Now, the featured image does not show up on the blog post. Even though I've set a featured image and you can see it there, it does not show up on the post. Also, when sharing to social media the featured image does not show up. I have Yoast SEO which enables you to set your own featured image and description and even those don't show up.
