Hyperlinks do not show in a different color

Hello,
Thank you for the free version of the theme. ??

Both in the post as well as page, hyperlinks do not appear in a different color and hence looks like normal text.
As an example in the link I’ve given, this text ‘exercise for defining happiness’ should display as a hyperlink. But doesn’t.
I checked all the theme options. Did I miss out on anything?

The page I need help with: [log in to see the link]
