Blog posts not loading

Hi there,

When I press “Load more posts” at the bottom of this page: https://www.marcograssiphotography.com/news/ the page starts loading but it never ends and I’m not able to visualize older posts.

On a side note, but less important, people seem not to be able to add a “heart” to my blog post.

Both things happen on laptop & mobile.

Please help!

Thank you
