Hello,

I have test your site as you are using “homeslider” and your second slide image not shown in the mobile devices.

When I test the second slide by changing image it displays the image So the conclusion is something is wrong with that specific image. You need to change the image which you used as a featured image in your second slide of homeslider from Slides >> homeslide2.
