Images Stopped Showing on Product Page

Hi,

I installed version 1.9.3 but I am unable to go into the Feature Image from URL settings. The page doesn’t load. I have used all versions 1.9.2 -> 1.8.9 since installing 1.9.2 version a few days ago that started all these problems and still the images don’t appear in the images area on my products page like it did before (https://ibb.co/gmrkYU).

I don’t normally use “Fake Internal Featured Image” but I tried with and without for all versions. The images display fine on my website except it makes my product slider not work properly which I believe has to do with the images now showing in the screenshot. How to fix? Thanks
