Getting 'invalid argument' error - fix?

[Anonymous]

I am getting

Warning: Invalid argument supplied for foreach() in /home/rf/phpGedView/useradmin.php on line 147

when I access the Admin/User Adminstration page and no users show in the list.  I can add a user and the login works properly.

This is only a problem in the MySQL version and you can fix it like this:

On line 146 of useradmin.php add the following line:
$users = getUsers();

Then add the following function to the authentication.php file:
//----------------------------------- getUsers
//-- return an array of user arrays
function getUsers() {
    global $TBLPREFIX;
    $sql = "SELECT * FROM ".$TBLPREFIX."users";
    $res = dbquery($sql);
    $users = array();
    if ($res) {
        while($user_row = mysql_fetch_array($res)) {
            $user = array();
            $user["username"]=$user_row["u_username"];
            $user["fullname"]=$user_row["u_fullname"];
            $user["password"]=$user_row["u_password"];
            if ($user_row["u_canadmin"]=='Y') $user["canadmin"]=true;
            else $user["canadmin"]=false;
            if ($user_row["u_canedit"]=='Y') $user["canedit"]=true;
            else $user["canedit"]=false;
            $users[$user_row["u_username"]] = $user;
        }
    }
    return $users;
}

Sorry about this error.
