oh no! I haven't.
I will do that and get back to you.
thanks

I suggest you contact you host immediately.

This does not have to do with your config file or your host. the databse can't recognise your details again.
Simply log in to your cpanel, locate phpmyadmin and then update the users table and look for your details. change your username and password.
if you don't understand this,
call 08133884165/ mail segzy54@gmail.com

Thanks.

Seems most people that encounter problems after the Wordpress 4.0 update are those that use iTheme Security and those that hid their dashboard login URL. Try copying your .htaccess file content to somewhere, then delete the file from your cPanel and see if you can login. When you have successfully logged in you can make your changes and return the .htaccess file content you copied.
