Bij een vorige website van mij heeft een formulier met captcha-code prima gewerkt. Bij een nieuwe site gebruik ik hetzelfde script maar het werkt nu niet. Maar ik krijg enkel de laatste alert over de verkeerde code te zien, ook al wordt de oplossing in het invulveld juist getypt. Wat kan er mis zijn?
