Common Reasons Your Links Redirect to a 404

This document lists the reasons your links may redirect to a 404 “page not found” error.

1. The most common reason is your permalink settings in WordPress. If permalinks are set to Plain, or to Custom with nothing in the Custom box, your links may return a 404 error. Set permalinks to the Post name option, found under Dashboard > Settings > Permalinks.
2. A page or post has the same name, which can cause a 404 error. Change the name of either the post or the page.
3. The destination URL for the post or page no longer exists or works. Make sure the destination URL is still valid.
4. A hosting server misconfiguration. Contact your host to troubleshoot why the pretty link isn’t redirecting correctly.
