Safari not loading images

Hi there,

Need help here…

Images on my website are not loading in Safari.
They did load at first, then made somes changes in the site (WP-SMUSH, W3 Total Cache, and others that were later reversed) and it stopped loading.

Tried:
UNICODE -compliant file names
Removing query strings from images
Removing Rounded borders (Visual Composer feature)
WP-SMUSH
Re-uploading images.

EDIT: Tried with and without Photon CDN.

Any ideas?

Thanks in advance!
