The DNN Captcha is not working for us in production on the Retrieve Password page in IE11.  Our production site has an SSL Certificate.  On test with the same exact code, and with no SSL certificate, it works.  On the Security page, we have already enabled SSL for the site.

- where is the Captcha being used? (module)
- if the is using http and not https? (check the page source, possibly)

It was an IIS setting that was causing the issue for us:

X-Content-Type-Options: nosniff

What this does is prevents the browser from hijacking mime types. Since the captcha uses text/html, the image of course would not be displayed. Problem solved.
