How to fix HTTP issues (500, 403, etc.)

What is an HTTP error? 

An HTTP error is a code returned by the web server when a user wants to access a web page. 

When this code is different from 200 (this means that the page is valid) or from 300 to 399 (this means a redirection), we can consider that the code is an error. 

Among these codes, we can find:

  • 401: Unauthorized
  • 403: Forbidden
  • 404: Not Found
  • 500 and 503: Internal Server Error
  • 504: Gateway Timeout

You will find the complete list of HTTP codes on this article of Wikipedia.
