What is Not Found?
When you enter a URL into your web browser and hit enter, your computer sends a request to the server where the website is hosted, asking it to return the web page to you. If the server can’t find the page, it returns an error with an HTTP status code of 404.
You might see a 404 error if you click on a broken link or if you mistype a URL. When you receive a 404 error, the webpage you were trying to reach cannot be found on the server. This can be due to an incorrect URL, a misnamed file, or an improper directive within the .htaccess file. You can see a 404 error when you try to visit a webpage, but the server hosting the page cannot find the page.
