i have that line in sessions.php
// Set her the corresponding database fields of the user table.
// If there is no corresponding field in the new user table,
// leave the value blank. Normally no need to change.
$user_table_fields = array(
"user_id" => "userid",
"user_level" => "usergroupid",
"user_name" => "username",
"user_password" => "password",
"user_email" => "email",
"user_showemail" => "",
"user_allowemails" => "",
"user_invisible" => "",
"user_joindate" => "joindate",
"user_activationkey" => "",
"user_lastaction" => "lastactivity",
"user_location" => "",
"user_lastvisit" => "lastvisit",
"user_comments" => "",
"user_homepage" => "homepage",
"user_icq" => "icq"
);
