While managing a WordPress website, you may encounter with some common errors, from which, 406 is also something you should learn about.

Not everyone sees such an error, but it refrains you from accessing a site. You need to learn about its cause and the solution.

When someone types an address of a website on the browser, the web browser sends a request to the server in the form of "Accept Header," and when the server doesn't find any file type browser asks, it displays 406 error.

Most of the times, the error occurs due to mod_security, a protocol web hosting companies apply to protect a website. If it tracks any violation of the rules, a 406 error or not acceptable error is shown on the screen.

In this tutorial, you're going to learn about solving the 406 or not acceptable error by disabling mod_security through the .htaccess file using cPanel.

I am sure; you already know how to edit such a core file.
