What is 404 error and how to fix it

Today I will tell you what a 404 error is and with what actions you can correct it. Many users when visiting sites encounter that after clicking on a link or entering a URL, the portal does not open, and a message appears on the screen stating that the page does not exist or it has been deleted (Not Found - “not found”, or 404 mistake). The cause of 404 errors can be either user actions or server or browser malfunctions or an unstable Internet connection. Also, the page may simply be absent at a specific address - the site administration transferred it to another URL or simply deleted it.
