Internet Explorer and ReCAPTCHA

FWIW — I’ve been working on a client’s site having a problem with reCAPTCHA form fields not being posted in Internet Explorer. The site had an XHTML Doctype but mark-up inside the reCAPTCHA iframe wasn’t compliant, which apparently threw IE off its game, although Chrome, Firefox and Opera had no problem with it.

Changing to a html5 doctype, “<!DOCTYPE html>” made everything just work, and there was no reason not to do just that in this case, but the internals of the ReCAPTCHA form might want some looking at before deploying the tool in production.

Again, For What It’s Worth.
