Posts pagination stopped working

The page with my posts shows that there are five pages containing posts, going back several months but the numerical links to get to these pages isn't working. I have purchased the Pro version and the problem still remains and I have not been able to find any reason why this stopped working. The page with the problem is: https://nucleationcapital.com/links/. PLEASE take a look and help me find a way to let people access these automatically-generated pages. This worked when I set it up and I have been adding posts for weeks, why did it stop working last week??
