MySQL Warning: supplied argument is not a valid MySQL-Link resource

From a PHP point of view, at any rate, this error is issued when you
call a function such as mysql_query() and specify a value for the 'Link
Identifier' argument which is NOT a valid database connection.
It suggests that the connection you are trying to use has been closed,
or has not been opened (or indeed, is NOT a database connection at all).
