Site Main content area not displaying after hosting migration

We just migrated this site https://www.kostalife.com to a new host digital ocean and everything is working well, except the main content area of each page is not showing up. The header, footer, sidebar, and top menu are all displaying correctly, but the central content is missing. I’ve checked the Admin area, and the page content is still there. I’m fairly certain that the files and database were moved correctly, This problem happens on all pages of the site, Any ideas would be much appreciated. thankyou
