How to Fix Server Error 400 Bad Requests in Elementor WordPress Website

Go through each of the solutions to force your server to accept the request you send from your browser:

1️⃣ Fix Errors in URLs

Having an error in the URL can trigger 400 error in the elementor website. We are not talking about a typo in the URL here. Rather, the error in the URL means not following the rules when typing a URL.

For example, you can not use “%” in your URL unless you are using UTM.

In the case of using UTM, you are allowed to add space in the URL but you need to use “%20” to insert a single space.

So, check whether you are using % or similar special characters that are not allowed in your URLs. If you find such an error, fix the URL to solve the https 400 bad request in WordPress.

2️⃣ Browser Cache Issue

Browser cache is the data that your browser stores in the form of copies of the web pages you visited. That way, it can load the content faster when you visit that site the next time. While the concept of browser cache seems like a positive thing to up user experience, sometimes it can cause many server errors including 400 bad request error.

So, if your URL is alright then you can try flushing your browser cache to fix this issue. Clearing cache and cookies in the browser is super easy. You can also press CTRL/CMD – Shift – R to push your request through.

CTRL/CMD – Shift – R

Note: You should either try your URL in the incognito/private mode of your browser. Or change the browser. If you don’t find any bad request error 400 in the private mode of the browser or in a different browser, then it’s probably a cache issue.

3️⃣ DNS Cache issue

The DNS cache is not the same as the browser cache. While both caches are in the process of saving relevant data to make previously visited sites load faster, there is a difference. The browser cache is saved by the browser and the DNS cache is saved by your system.

So, if clearing your browser cache doesn’t help to resolve the HTTP 400 server error in WordPress, then you can try flushing the DNS cache.

To flush the DNS cache in Windows, go to the Command prompt and type the following command:

 ipconfig /flushdns

To flush in Mac, go to the terminal and type the following command:

sudo dskacheutil -flyushkahe; sudo killall -UP mDNSResponder

4️⃣ Conflict with Browser Extension & Addons

The third-party add-ons or extensions you are using on your browser can also create conflict with your server request resulting in 400 bad requests. 

You can solve this issue by disabling each extension one by one to see if the server error 400 bad request in Elementor is resolved.

5️⃣ The File is Too Large For the Server

To ensure this is a size issue, try to upload a smaller file. If the smaller file gets uploaded successfully without any server bad request error, then you can be assured the file you are trying to upload is too large for your server.

However, you can fix it by increasing the WordPress memory limit. For this, you need to navigate to the wp-config.php file and then update the “define(‘WP_MEMORY_LIMIT’, ’64M’)” line. You need to replace “64M” with either 128M or 256M.

define(‘WP_MEMORY_LIMIT’, ’64M’)

Note: If increasing WordPress memory doesn’t help, then try to update the max_input_vars variable to 5000. You can update this value from the php.ini file.
