Have you ever experienced a 400 Bad Request error while browsing the internet? Or when you’re editing a website, a 400 Bad Request error suddenly appears? Don’t worry because you’ve come to the right place!
In this article, we will discuss in full how to fix WordPress errors. Especially regarding how to deal with 400 Bad Requests. Starting from what the 400 Bad Request is, its causes, and of course how to deal with it.
What is a 400 Bad Request?
Error 400 Bad Request is an error that occurs when the server does not understand requests from website visitors. This misunderstanding is caused because the request is incorrect or corrupted in the middle of the data transmission process.
This 400 Bad Request will display a different error on each website. Here we provide a list of 400 Bad Request errors that generally occur:
– 400 Bad Requests
– Bad Requests. Your browser sent a request that this server could not understand.
– Bad Request – Invalid URL
– HTTP Error 400 – Bad Request
– Bad Request: Error 400
– HTTP Error 400. The request hostname is invalid.
– 400 – Bad request. The request could not be understood by the server due to malformed syntax. The client should not repeat the request without modifications.
The list of errors above occurs for a number of reasons—which we’ll cover right below. But generally, these problems are on the client side (website visitors), not on the server side.
Causes of 400 Bad Requests
There are several things that cause 400 Bad Requests, namely:
1. Inappropriate URLs
The 404 Bad Request error can occur because you entered an incorrect URL, the syntax is problematic, or the URL contains characters that are not allowed. Below is an example of a URL with disallowed characters that the server cannot process:
https://www.niagahoster.co.id/blog/cara-mendapatkan-uang-dari-internet%
You can see in the URL above there is a % character which shouldn’t be there.
2. Corrupted Cache and Cookies
Even if the URL you typed is 100% correct, the 400 Bad Request error can still occur, you know. This is usually because there are files in the browser cache and cookies that are expired or corrupted. Well, the cache is a place to store temporary data belonging to the website.
You may have experienced this when trying to log in to WordPress after a long time of not logging in. This happens because your log in cookie is corrupted, so it can’t provide admin authentication like it normally does. Eventually, your connection is rejected and a 400 Bad Request error appears.
3. DNS Cache Problem
This DNS is responsible for changing domain names into IP addresses that computers can understand.
The data from the DNS conversion process is stored locally on your computer in the form of a DNS cache. Well, the 400 Bad Request error can also occur when the DNS cache data stored locally does not match the DNS on the current website. Maybe the DNS of the website has been updated or changed.
4. File Size is Too Large
Another 400 Bad Request cause occurs when you upload a file that is too large for the server to process. Each server has its own limitations, so this 404 Bad Request error varies for each website.
5 Ways to Overcome 400 Bad Requests
Below, we will explain how to deal with 400 Bad Requests. Oh yes, methods number one to four below can be done by visitors or website owners. Meanwhile, method number five is a special solution for website owners only. Good luck!
1. Double Check the URL Typing
The first way to try is to double-check the URL that you just typed into the browser. Even though it sounds trivial, this typo is the most common error related to 400 Bad Requests, you know.
So, make sure that the domain name and the page you want to access are correct. Check once again that the URL is indeed separated by a hyphen (–). If the 400 Bad Request error still appears, it’s time for you to try the second method.
2. Clear your Browser Cache
The 400 Bad Request error can occur if the website files stored by your browser locally are damaged. These files are:
– HTML
– JavaScript
– Text/config files
– CSS
– Media (image, video, sound)
– Data files (XML, JSON)
The files above are automatically saved by the browser the first time you visit the website. This is because this cache helps the browser work efficiently without the need to download the same file every time you visit the website. Therefore, you need to clear the browser cache so that the old, corrupted data is removed.
How to? If you use Google Chrome or Mozilla Firefox, you can follow the guide at →How to Clear Cache in Chrome Without Hassle!.
However, if you are using Microsoft Edge, Opera, or Safari, you can find instructions for clearing the cache in →How to Clear Browser Cache
3. Clear Cookies in Your Browser
If clearing the browser cache still doesn’t work, you can try deleting browser cookies as well. One website can use dozens of different cookies. If even one of these cookies is expired or damaged, a 404 Bad Request error will appear.
For example, using Google Chrome, you can delete cookies by clicking on the three-dot icon at the top right, then selecting More Tools > Clear Browsing Data from the pop-up menu that appears.
After that, make sure that you have checked Cookies and other site data and Time Range is at All time. If so, just click the blue Clear Data button.
After the cookies are deleted, you can reopen the website which previously had 400 Bad Requests.
4. Clear DNS Cache
A corrupted DNS cache can also be the cause of the 400 Bad Request error. Therefore, you should delete all stored DNS (flush DNS) records on the computer.
5. Compress Files Before Uploading to the Website (Specially for Website Owners)
As we mentioned above, one of the causes of the 400 Bad Request error is that the file size uploaded to your website is too large.
Some hosts do limit the size of uploaded files from each website and sometimes they are not transparent about this.
The solution for this 400 Bad Request is to try uploading a smaller file first. If it works, it means that the previous file was too big and you need to compress it.
As for video files, you should first upload them to YouTube instead of directly uploading them to the website. Because, generally even though it has been compressed, the video size is still larger than the hosting limit.
Now, after the video is uploaded to YouTube, you can embed the video on the website.
Conclusion
After reading this article, you don’t need to worry when you get a 400 Bad Request error because there are several ways to deal with this 400 Bad Request. Error 400 Bad Request is generally a problem caused on the client (visitor) side, not from the server side. So, if you are a website owner, you don’t need to panic about this error.
However, there are times when the 400 Bad Request error occurs on the server side. If you have this, the only way that can be done is to contact your hosting party. Therefore, make sure that your hosting customer support is always available 24 hours to help you.
