I hardly see posts going back 24-48 hours on my Facebook wall. I’ve heard about a “View older posts” hyperlink at the bottom of the page. However, in my case, I only see this remark: “There are no more posts to show right now.” and an “Edit Options” hyperlink at the bottom. Facebook’s help pages are of no help. I’ve logged a ticket on Facebook support and attached a screenshot, there’s still no reply.
