Blog Post Page Empty

Hi. I had to install a blog grid plugin to make blog posts appear at this link: https://hotellivingbook.com/press/ and if I disable it and set this page to the default blog post page the page appears blank but the footer and menu remain. Is there a simple way to make the blog posts re-appear without the plugin & has anyone else experienced this before with this theme?

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