Check File Permissions

File rights are a more technical part of running a WordPress site. Almost always, a 401 error is caused by a wrong file entry. Make sure that the right people can view your files and folders so that WordPress can work the way it was meant to.

Disable Security Plugins

A popular way to keep your website safe is to use security apps. But sometimes these plugins are too good at what they do and block legal calls, which can lead to problems like the 401 Bad Request error. Try turning off your security apps for a while to see if the problem goes away.

Monitor Your Hosting Server

Problems can sometimes be brought on by problems with computers. If you’ve tried all of the above steps and still can’t get your site to work, you should call the company that runs your site. They can check the health of your server to make sure that the 401 error isn’t caused by how it’s set up. Keep in mind that for a website to work well, it needs a good server.

Review Your URL Structure

How your WordPress site is set up in terms of URLs is less complicated, but just as important. When URLs are set up wrong, problems like the 401 error can happen. Check the URL settings on your WordPress site to make sure they match how your site is set up.

Investigate Your Theme

The theme you choose will have a big impact on how your WordPress site looks and how it works.

This step can help you figure out problems that might be caused by special settings or mistakes in your. htaccess file.

Disable Mod_Security

In line with the theme of server problems, Mod_Security, a server package meant to make the web safer, could also be to blame. But sometimes it’s too strict and turns down requests that should be granted. This is why the 401 Bad Request error happens. If you think Mod_Security is the problem, call your hosting company and ask that it be briefly turned off so you can figure out what’s wrong.
