Testlink 1.9.1 error (adodb-mysql.inc.php)

[fyl]

E_WARNING mysql_connect() [<a href='function.mysql-connect'>function.mysql-connect</a>]: Access denied for user 'root'@'localhost' (using password: YES) - in /usr/local/httpd/htdocs/testlink/third_party/adodb/drivers/adodb-mysql.inc.php - Line 364 Session information

I am getting this in the events. I can't tell what database is trying to be accessed and I can't think why root@localhost would be attempting to do this call.
