Wie kan mij helpen met het Facebook login op een website?
Ik heb een website waar je altijd via Facebook kon inloggen, dit heeft altijd gewerkt maar blijkt op versie 2.2 te zijn gemaakt.
Inmiddels zitten ze op versie 3.2 en nu werkt het niet meer en krijg het ook niet werkend momenteel.
Wie heeft er zin en tijd om mee te denken zodat het weer werkt.
Dit is de fout wat die nu aangeeft:
