I have WP 3.1.3, the latest Gravity Forms version, and the latest WPTouch Pro (2.2.4) for the mobile theme. The forms render fine in mobile, but the reCaptcha doesn't work. On the moble pages, Initially, you get a "?" symbol, and if you click the little refresh/new word pair button, you get the error "Input Error: Invalid referer".
Is there any solution to this; I do not want to eliminate the reCaptcha and would prefer to avoid trying to use a different forms plugin.
The test site I am deploying this on is private, but I can provide credentials via email if you want to access it. Thanks!
