Slider images/icons with animation are not displaying!

Hi there – hoping you can help! Suddenly almost all of the images on my site stopped displaying. All sliders show up as blank and images with pop up animation do not appear at all. Icons with animation appear (as small), but animations do not work.

Only images without any animation are displaying. As an example, this can be seen on this page: http://www.lokaltravel.com/about. The only image that displays properly is the still image from ‘team member’ avia layout.

I have deactivated all plugins and nothing changed. I’ve also tried creating new pages or recreating content on existing pages, but images still do not display.

I’m including WP login credentials in private content. Any help you can offer is very much appreciated!
