Featured images not showing !! Please help!

Hi all!

Im fairly new to this so I know little about coding but I hope to learn quickly! I recently changed my theme to Soledad and none of my featured images show on my home screen. I have regenerated all my images and tried re uploading the featured images but nothing seems to work. I also disabled any plugins not associated with my theme. My site is https://noshoesontuesdays.com . Does anybody have any idea why this is happening? Thank you in advance!
