Media Library and Feature Image Issue

I started facing this problem when it all updated to 4.2 The Media Library is showing any of my previous images. It shows a blank window.

Then, when i click “set featured image” link to set an image to an article, it opens a window but as it is connected to “Medial Library is it shows nothing. Then the button “Select files” then it does not uploads the image as well. The other tab of “Media Library” does not work as well.

I mentioned this yesterday but got any help. Kindly people, if someone guide or fix this issue.

Thanks,
Faheem
