WordPress – Viewing a Single Post Gives a 404 Error

If accessing a single post gives a 404 error, then the error is most likely in the permalink structure. See the following instructions to fix the error.

If the custom code starts with something else, change it to this. Making this change should allow the linking to work properly and should remove any 404 errors.
