Portfolio images not showing on page

Hi,

Sorry for posting two questions at the same time…

I just uploaded the Boldial theme and child theme and activated it, and I also did the “Import Demo Content”.

I assigned a page as a static homepage and placed the Portfolio element in it and found out that portfolio images are not showing, you just see hover effects when you place mouse pointer across the area where an image should be (the website: https://pigtelligent.com)

I also uploaded some of my own test portfolio projects, with the same result – images are not showing on homepage.

The permissions for “wp-content” folder are set to 755, and for “uploads” folder 777.

Please tell me if you need any other information?

Thanks,
Milosh
