Our recaptcha elements on our form pages have started to be blocked on pages in IE. Our forms are HTTPS, and IE blocks the recaptchas because they aren't secure content. We have seen a significant drop in volume from these forms in the past few months, and now I'm guessing this is the reason.
How can this be fixed? Do we even really need recaptchas? I put them on there because it seemed like a good way to block spammers, but how necessary are they for security?
Thanks for your help!
