HTTP in Dateien und Anhängen gelöscht

Hi,
wenn ich das mache geht keine funktion mehr.
Ich zeige es mal im Bild
Da müsste unter https  auch http stehen.
Und dieses http habe ich gelöscht und weiß nicht wie ich es wieder da rein bekomme.
Wenn ich den Ordner/Datei handlers.json lösche ist da gar nichts mehr drin.
Also habe ich eine Sicherheitskope von der Datei gemacht und wieder reinkopiert.

Da steht dann sowas drin:
