Recently the links to my previous posts have started to return error codes. Thinking this might be caused by an outdated version I updated WordPress and all widgets. Still no luck. For "Archives" and "Pages" and "Categories" I return the error "404 Page not found" but on the "Recent Posts" sidebar the links are not clickable. For external links the links/pages load without error.
