Previous Entries link doesn’t work

I’m new and have just started a blog https://www.loades.net/another%20day%20on%20the%20buses/ todays posting meant that I got a ‘Previous Entries’ link at the bottom of the hompegage ….. but clicking the link doesn’t work. The same link works if you do it from the Archives Feb 2007 page.
What have I done wrong?

Thanks.
