If you're getting this message "We're sorry, the page you requested could not be found Return to the home page You will be automatically redirected in 5 seconds." Then there's a chance you're using a plugin, addon or script on your website that's redirecting you away from your cPanel or webmail login.
cPanel and Webmail redirection problem solution
If you're getting redirected away from your cPanel or Wembail because of an over controlling plugin, addon or script, just uninstall the script, addon, or plugin and the problem should go away. If you don't want to uninstall the script, addon, or plugin, you can access your cPanel and Webmail another way.
Try accessing your cPanel by entering the IP address followed by a slash and the word 'cpanel' into your web browser URL field.
Try accessing your webmail by entering the IP address followed by a slash and the word 'webmail' into your web browser URL field.
Your login details will be the same.
