Older Posts Problem

Dear Friends,

I own malclarke.com and I imported 200 or so posts from my blogspot blog to the site. This was done without issue.

The Problem

1. Go to the bottom of Malclarke.com and click “older posts”, this goes to page 2, https://malclarke.com/page/2/ scroll to the bottom of that page, click “older posts” again and it should go to page 3, but it does not. It goes back to page 2. See malclarke.com/page/3/ (I’m guessing this would be the link.

This means my previous posts are effectively lost unless the permalink is known.

Any ideas or solutions please? I’ve not changed anything or amended the editor.
