It is always frustrating when we try to visit a website of interest and, suddenly, the browser we are using ends up showing us an access error , which could be a sign of a momentary (temporary) or permanent incident. Be that as it may, the truth is that depending on the error code that appears we could know it in advance.
Not surprisingly, a 404 error is usually one of the most common error codes. And even if the developer of said web page has chosen a curious and surprising design, the message is always the same: page not found .
It is, in fact, one of the most frequent errors, which basically means that almost all users, experienced or inexperienced, have encountered it at some point. What’s more, statistically, it is quite possible that each of us has already encountered a 404 error while surfing the net. But why does it appear and what does it mean? Is there something the user can do to solve it?
What is a 404 error?
A 404 error , which is usually accompanied by the message “Page or file not found” consists of an error code that belongs to the HTTP communication protocol on the Internet.
Specifically, it is an error code sent by an HTTP server when the resource requested by the user could not be found (in most cases it will consist of a specific URL or web page address, although it can also appear in case of not find files such as images or videos).
In short, any user who sees a 404 error message when trying to access certain web content must understand that the page they are looking for does not exist at that time, even though it did exist previously.
Depending on the website developer, it is possible that the design of that 404 error page has been customized with funny messages, that it redirects the user to an equivalent functional website or that it simply includes a search form where to find information within the website. that interests us.
Why happens? What are the causes of a 404 error?
Actually, there are several situations that can cause the appearance of a 404 error. Here we discover which are the most common:
- The link the user is trying to access has been removed. That is, it no longer exists.
- The link, when the user enters it manually in the address bar of the browser, contains some syntax error.
- The link in question has a redirect, but it has not been configured correctly.
- The problem comes from the server (although it is, by the way, a rather rare error).
In most cases, there are two reasons why this error can appear. How many times have we wrongly entered the URL of the page we want to visit in the address bar of the browser? It is, in fact, usually one of the most common causes. Luckily, in these cases the solution is usually as simple as correcting the error, or retyping the address (this time correctly).
However, it is also often the case that the webmaster or website owner has simply decided to remove that page, but without removing some of the links that still continue to lead the user to it. It is true, this is usually one of the most frustrating causes, since in these cases the user can really do little.
Can we fix it?
Unless we are the owner of the website we are trying to access there is really little we can do , since it is an incident that does not depend on us as users or readers of the site in question. Unless, of course, we were the ones who entered the URL incorrectly.
Enter the URL correctly
Sometimes, due to the rush, it is possible that by manually entering a certain URL in the browser’s address bar we end up typing it wrong. So, in the end, the mentioned 404 error ends up.
Whenever this happens, it is worth checking if the URL is correct , or if any letters are missing or even if we have entered a character where it really should not go.
If we notice – and find – the error, the solution could come from our hand, since it will be enough to write it again .
Making use of the Internet Archive
Whether you are sure that the page you are trying to access existed previously, or not, it is possible to review the Internet Archive to see whether or not we can access the content that existed a while ago.
Internet Archive consists of a wonderful digital library, managed by a non-profit organization, in which millions of web pages are preserved, being able to review completely free how a website looked at a certain moment.
Of course, this option will be valid when that particular URL we are trying to access has been around long enough for the Internet Archive to have captured its content.
To use it, it is as simple as entering the URL we want to access in the ‘Wayback Machine’ search form. If all goes well, a search result will appear with a series of captures collected over time. To view it, you simply have to click on some of them.
