That's a very common one. You're on windows, right? Try putting in "consider upgrading MySQL client" into google. The first one I found was this one: http://www.experts-exchange.com/Web/Web_Languages/PHP/PHP_Windows/Q_21252231 .html Although the guy first claims it's not the OLD_PASSWORD problem, believe me, it is. Alternatively look up the error code, although I don't know if that would've helped in this case. -----Original Message----- From: W Roothman [mailto:willows@xxxxxxxxxxxx] Sent: 13 October 2005 06:18 To: php-db@xxxxxxxxxxxxx Subject: MySQL Connect using Dreamweaver Dear All, I have installed MySQL 5 with PHP 4.3.3.
