Archives and Older/Newer links not working

My site superkain.net seems to have lost the place to point all the links for older/newer and archived portions of the site. Whenever you click on one of the links, it just takes you back to whatever page you were on.

If I am at the main page https://superkain.net then all of the links show as links to https://superkain.net. If I am on any other page, then all those links show they return to the current page. I don’t know where to start looking.

Has anyone seen this? Help?
