When sending PM's, the ReCaptcha module is displaying this:
(https://forum.vc-mp.org/proxy.php?request=http%3A%2F%2Fwww.gstatic.com%2Frecaptcha%2Fimages%2Fv1_unsupported.png&hash=a3d020846aeb00f9332e0ba9173f0fb2a008b892)
ReCaptcha released updates long ago, so there is no reason why Version 1 should still be implemented. Please update it! This is blocking certain features on the forum from being used.
Write reCAPTCHA V1 IS SHUTDOWN in the box that asks for the captcha text. It worked the last time I used it on another site.
