We are using the plugin Really Simple Captcha in a Contact Form 7 contact page.
The page has not been changed since 9/9/2014.
Please look at http://rain1.com/new-site/customer-support/service-request/
. Note the captch text box at the bottom is empty. Thus, no one can submit a form.
See attached files of the form & the captcha_form.jpg.
I tried deactivation the Really Simple Captcha plugin & re-activating it. Still the same. I thought about downloading the latest version (the current one is NOT the latest), but I'm afraid that might screw it up worse than it is.
