I turned off all of the plug-ins that weren’t part of the theme bundle. This did not solve my problem. Neither did the recommended plug-in, as I had already selected featured images for the posts that aren’t showing them. The featured images show up when using the free version but disappear in Pro. The strangest part is that it is not all of them.
I did go in and reconfigure the settings in Agama Pro to match what I had in the free version. What I am saying is that the featured images for each post, which have already been set in each post individually work properly in the free version, but do not appear when using the Pro version.
