Category pages don’t appear after SSL

I switched to SSL using Really Simple SSL. Since the change (possibly before, but only noticing now), when we click on the NAV on the home page that should take us to categories, nothing appears on the category pages. My posts show that there are posts in those categories but nada.

Is there someplace I can look? I tried clean up SSL and such but none worked.

I’m not a coder but I’m not afraid to change codes and do take directions well.
