Missing SSL padlock icon in Safari address bar

When I go to https://www.frameforge.com in Safari, the address bar doesn't contain the little padlock icon indicating proper SSL. But if I go to the same URL in FireFox, Chrome, or Edge, they do have a lock indicating that all is well. How can I figure out why Safari is not happy with this site's certificates or whatever?

Looking at the Console tab of Safari Web Inspector, looks like there's a warning for mixed content. Fixing this will likely show the padlock icon.
