Image carousel broken and section nbackground video not working

Hi,

Recently one of my client – websites broke. The video background of the section does not work any more on the frontend.

And an image carousel below the hero section where the video is, has also broken.

Checked everything, disabled all plugins except for Elementor. Nothing works.

I replaced the video with an image as the section’s background and that works fine but as soon as I try to use the video again, that section again becomes on the frontend.

The image carousel section too, does not come what may.

Surprisingly, everything looks fine when I open the page in Elementor.

Please help!
