Self-installed WP: blog posts not appearing on homepage

Hi, everyone!

I run the website for our company. I’m not a programmer. It’s a small two-person company, I basically have to do it alone.

We’re changing to a new server host soon, so I tried backing up and duplicating our website to a test area in our new server.
With a few minor exceptions, most things went by without a hitch… except that the blog entries are not appearing on the homepage, as it’s supposed to.

Please check out what I’m describing:

– this is the URL for the actual website with the first 10 blog entries bellow the big banner: https://www.audiolog.pt

– and this is the URL for the test website (note: the big banner is missing on purpose. It’s the missing blog posts below that are puzzling me): https://www.the-microphone-spa.com/audiologtest

Could someone please advise on how to proceed?

How can I make the blog entries appear to complete the website duplication? Not sure how to go from here…

Thanks!
