Hi There,
Hi show the add to cart button please follow like below:
go to the file: \app\design\frontend\Ubertheme\megamall\Magento_Catalog\web\css\source\module\_listings.less at line 
153 and change like this:

  .product-item-inner{
    display: none;
  }

change to:

  .product-item-inner{
    display: block;
    .actions-secondary {
      display: none;
    } 
  }

When done please re-compile LESS -> CSS.
Step1: go to root site with CLI and type: 
rm -rf var/* pub/static/*
Step2:
php bin/magento setup:static-content:deploy -f
It will be working fine. 
Please let me know if you need help further.
