[Theme: Pace] Need help activating Thumbnails

Hi,

I’m new to self-hosting, and hope there might be an easy solution just outside my reach!

I bought the Pace theme, which appears to support ‘featured image’ by the way the demo looks (https://www.mojomarketplace.com/item/pace-stylish-portfolio-and-blog-wordpress-theme/demo/52c6fef6-990c-4799-bfa4-44c40a141536 and https://www.mojomarketplace.com/item/pace-stylish-portfolio-and-blog-wordpress-theme/demo/52c6fef6-990c-4799-bfa4-44c40a141536)

However, despite having ‘featured image’ activated and set up on each of my posts that I migrated over (from https://thecircusdiaries.com), all I am getting in my excerpts is text (https://66.147.244.83/~thecire2/)

Hope someone can point me in the right direction!

Cheers,
Kate
