I'm trying to create archives of different post types. For example, I have a custom post type called "Regions" with multiple posts. I created an archive in the Toolset dashboard, and added blocks to the loop. When I try to view the page: hidden link
It only shows pagination, but none of the content. I can view the individual posts, here's one example: hidden link
I took a look at this for you and managed to create a copy of your site to setup here locally to see if it an issue with your server and it actually is.
Take a look at my screenshot. As you can see the post shows up fine when I test this site on my local server.
The first step I would do is to ensure that your server requirements meet our minimum requirements. To know these requirements I would recommend going to the link below. https://toolset.com/toolset-requirements/
