I have written a short post for my WP blog based on a child theme and I have seem to have accidentally set two Feature Images. I really, just want one - twhich I can select from the media library. I then should see my excerpt text situated alongside it. Whereas I am seeing the second image and that meaningless [Gallery] tag. Any ideas as to how I can fix this? I think I added or attached the second image somehow so I just need to remove it.
I am happy to go into the content database if this is what's required.
