We cant make on for you, but the install.php looks like it should work. From what i see, if you opened up your install.php and ran it, and it checked as ok. then it should work after making the table. There must be something wrong in the config file. But keep host as 'localhost'.
CODE
$db_table = "tbllogin"; //The table that was created from install.php
change that to
CODE
$db_table = "users"; //The table that was created from install.php
and try using this script to make table.
CODE
<?php
$linkID = mysql_connect('localhost','login','password')
or die("Error,database not accessing!");
mysql_select_db('masterdb',$linkID);
CREATE TABLE 'users' (
'id' BIGINT(11) DEFAULT '0' NOT NULL AUTO_INCREMENT ,
'username' VARCHAR( 25 ) NOT NULL ,
'password' VARCHAR( 25 ) NOT NULL ,
PRIMARY KEY ('id')
);
?>
