Using the recaptcha javascript client ( http://www.google.com/recaptcha/api.js?onload=vcRecaptchaApiLoaded&render=explicit ) the automatic request (GET https://www.google.com/recaptcha/api2/userverify?k=XXXXXXXXX) after you select the correct images returns an invalid json which afterwards is sent to back to google and their json validation fails. This worked as expected for months now. Not anymore :(
Server side library used reCaptcha PHP (1.1)
