Het gaat om het stukje waar hij zegt: Als username en password empty zijn, echo dan : You must fill in username and password.
Maar ik heb het dus wel ingevuld, en beide velden zijn gewoon ingevuld. Kunnen jullie in 1 van deze 2 php's een fout vinden?

zet dit achter regel 8 van je login.php
Code (php)

$username = $_POST['username'];
$password = $_POST['password'];
$password = $_POST['password'];
edit:
never mind, vervang in login.php dit:

echo "You must fill in username and password";
// Else if everything is ok continue with code
} else {
// Include config file
include "config.php";
// Define variables
$username = $_POST['username'];
$password = $_POST['password'];
if ((empty($username)) || (empty($password))){
echo "You must fill in username and password";
// Else if everything is ok continue with code
} else {
// Include config file
include "config.php";
// Define variables
$username = $_POST['username'];
$password = $_POST['password'];

Enig idee hoe dit kan?
Ik heb dit script gedownload, dus niet zelf gemaakt, dus ik probeer het zo goed mogelijk te snappen...

Oke, sorry dat was mijn eigen fout, heb het nu opgelost, ik had jou vervanging er zo in geplakt, dus het ging allemaal een beetje dubbel! Dankje! Alles werkt nu goed!
