what do i need to do?
I get the following message when I try to log into the wp-admin. Earlier this morning it was working just fine, now it get this error…

<i>”Error establishing a database connection! This probably means that the connection information in your wp-config.php file is incorrect. Double check it and try again.

Are you sure you have the correct user/password?
Are you sure that you have typed the correct hostname?
Are you sure that the database server is running? “</i>

Can someone help? Thanks
