Featured images are not loading in Safari or Chrome browsers, Firefox works fine. The first 9 featured images load, post images after that are not loading.
I did just that and the issue persisted. I just tried it again and it did not make a difference. Actually, the problem is now the same on all the browsers.
The problem is now resolved. When I disabled all the plugins except for GP Premium it restored the featured images. As for the rest of the images not showing up, I apparently did not set a featured image for the older posts. I have another website I manage with the exact same setup and was able to restore the featured images by disabling all the plugins except for GP Premium.
