i bought your awesome theme! But the thumbnail is not showing up. i work with xampp so i can’t show it to you but added 2 Screenshots. First is where the portfolio thumbnail is select and the second screenshot is what shows up on the page.
How are you adding the portfolio to the page?
In my case, I added a Jkreative Portfolio Block Wrapper. Within the wrapper I added a Portfolio Block Item. Within the item I select the portfolio I created. I can add a portfolio image which is what you are missing here. This gives you the same effect as shown in the Villa demo of this theme.
