Older posts are not visible

I’m holding a foodblog and I’m putting blog posts online on a regular basis.(www.happinessishomemade.be). However, I recently noticed that, on every page, only my latesyt 10 blog posts are showing. Normally, on the bottem of the page you should have the option to navigate to older posts. You should be able to see : page 1-2-3-4-5.. However, it appears missing on al my pages. Of i’m posting a new blog article, the last blog post on that page will dissapear and is not tracable anymore for my viewers.

Can anybody help me with this issue?

Thank you!
