Upgrade database error

[theologyonline]

I am trying to upgrade a vBulletin 2.3.4 to the latest vBulletin software.

When I try to run the upgrade script I get the following error.....

Database error in vBulletin :

mysql_connect(): Client does not support authentication protocol requested by server; consider upgrading MySQL client
/home/httpd/vhosts/mysite.com/httpdocs/forums2/includes/class_core.php on line 274

MySQL Error  :

Referrer     :

Any ideas as to what I should check?

In your config.php file what mysql type did you select?

I used....

mysql

I tried using a few other options just to see if they would work and they didn't.

Here is what I am trying to do....

I want to leave my board open so I made a copy of my database and installed the new vbulletin software in a different directory "forums2" I would like to update this "copy" of the forums and database so I can get my forum all updated before I open it to my members.

I have double and triple checked all my forum paths and they seem to be OK.

Also, on this same server I have a current vBulletin running on another website so my PHP and MsQL versions should be compatible.

Any ideas?
