sliders not working now

Something has happened to my Slides…

I use MasterSlider, which I have asked them, but they are slow in responding and this is a live site.

Somehow the slides are not showing up even though I have them there and can see them and such in the settings of MasterSlider.

You can view it at https://sweetwatervacationrentals.com right on the home page I have 3 sliders and all three are not working…

But still nothing is working, can you please help as this is a live site. Everything was working before, not sure what happened? I do use TinyPNG (have since deactivated this), Ewww (deactivated to figure if plugins are messing with it-but need this back for the speed), and W3 Total Cache as plugins. Also I don’t use Photon on Jetpack as that has messed with other sites I tried it on.

I’d hate to redo all three of these sliders as I have many pictures in each. Any suggestions would be very grateful.

thanks
