The redirection of the WordPress website, from HTTPS to HTTP can be achieved by changing the rules in .htaccess file, regarding website protocols. Follow these steps:

Go to cPanel > File Manager. Click on Settings button in the top-right corner and enable “Show Hidden Files (dotfiles)”.

Navigate to website's root directory or folder and select “.htaccess” file. Click Edit button on top, and at the end of .htaccess file, add the following text:

RewriteEngine On
RewriteCond %{HTTP} ! =on
RewriteRule ^(. *) http://%{HTTP_HOST}/$1 [R=301,L]

After text is added, click the “Save Changes” button located in the top right corner. Now the site should redirect to HTTP.
