If you have a website, you’re going to encounter HTTP error codes at least once in your life.
There could be more than one reason for an HTTP error response code. It might occur because a web page is no longer available (404 not found) or because of a problem with the server (500 internal error).
In this post, I’m going to tell you what HTTP error codes are. This will help you better understand the HTTP responses.
After that, I will discuss the most common HTTP error codes along with some tips to fix each code.
What are HTTP error codes?
HTTP status codes are responses issued for a client’s request made to a server. For example, when your client (your web browser) tries to connect to your WordPress site (the server).
Based on how the request is handled, the server shows different responses. These responses include redirects, server errors, client errors, and others as such. HTTP error codes are not part of web pages; instead, they are responses from servers about how the request is handled.
Not all HTTP status codes indicate errors. For example, some just communicate that a page has been moved, either permanently or temporarily. But if you are experiencing errors, the HTTP error codes that you see will help you figure out what the problem is.
Now that you know what it is, let’s dig into some of the most common HTTP error codes and status codes and how to fix them.
Seven most common HTTP error codes and status codes
“401 Unauthorized”
First on our list of HTTP error codes is 401. A 401 message means the server received an unauthenticated request.
In this error, a message announces that the page couldn’t load because of invalid credentials for whatever reason.
How to fix it?
It could be possible the login URL has changed, or the URL you entered is incorrect. However, if that’s not the case, try clearing the browser cache and cookies.

“404 Not Found”
A 404 status code is a common HTTP error code on the internet. This HTTP response is generated when a page the user is looking for cannot be found on the server. There could be multiple reasons behind 404 occurrences. Perhaps because the webmaster has deleted the page or the URL you have entered is incorrect (since it’s a client-side error).
How to fix it?
Fixing a broken link (or, more specifically, a 404) is still an essential maintenance task. If you are glutton for work and won’t mind taking the longer route, use the .htaccess method. But a more natural way to do this is by installing the Redirection plugin from the WordPress directory. You can then redirect it to any webpage on the site.
