How to troubleshoot a 404 Not Found error

What 404 means

A 404 error means the requested page or file could not be found at that address.

Common causes

  • The URL was typed incorrectly.
  • The file was deleted or moved.
  • The link points to the wrong location.
  • WordPress permalinks need refreshing.
  • DNS or document root settings are incorrect.

First checks

Confirm the file exists, check the spelling and test from another browser.
