Thanks for that have checked and corrected. Now when I try to log into to admin I get the message below. I have checked the DB user name and password and they are correct and the same as my SQL info. The server is not down. I have the host name down as localhost. Think I have run out of things to try, feeling very stupid at the moment.
Error establishing a database connection
This either means that the username and password information in your wp-config.php file is incorrect or we can't contact the database server at localhost. This could mean your host's database server is down.
•Are you sure you have the correct username and password?
•Are you sure that you have typed the correct hostname?
•Are you sure that the database server is running?
If you're unsure what these terms mean you should probably contact your host. If you still need help you can always visit the WordPress Support Forums.
