Insert Media loading problem

Dear Support Team!

I’am woking with Enfold and would like to paste some images on one of the pages of my website, but when i choose insert media option, it starts to load the pictures what are uploaded but after few successful loads the loader seems to be struck and nothing happens if i scroll down, also some of the pictures only have the frame and the picture is not shown.

I have tried to refresh the browser but it didnt help. I have checked on all possible browsers and all of them updated to the newest version. (Chrome/Firefox/Opera). Java updates also installed. Also checked it on few PC-s and was the same on all platform.

Here is an image of the insert media screen what happens after few seconds of loading.

Would like to ask for help, how can i solve this problem?

Thank you!
