If I used "localhost", the script running well. But if I used Server name or IP address, the error message displayed : Warning: mysql_connect() [function.mysql-connect <http://tu-lip-nt4/CMS/forecast/function.mysql-connect> ]: Host '157.47.115.180' is not allowed to connect to this MySQL server in c:\wamp\www\CMS\forecast\includes\db_connection.php on line 10 Error !!

There is normally always a password on root. Also, I would be a little more careful of pasting your IP Address into a message forum. I'm sure we are all honest people but you never know. Coupled with your DB name we can now look at your data if we get in. You didn't tell us what the error was when using 'localhost' versus the IP address. What does it say then? -----Original Message----- From: Nur_Adman@xxxxxxx [mailto:Nur_Adman@xxxxxxx] Sent: Wednesday, March 29, 2006 2:31 PM To: php-db@xxxxxxxxxxxxx Subject: Cannot connect to MySQL using Dear All, I need some help.
