I just installed Contact Form 7. I am using a Child/Custom Theme. The url is http://www.bodybyginny.com. I tried deactivating some other plugins that might be causing a problem, and also took off the Captcha that I had added, but neither approach worked. If you try it you will see what I mean. Can you please suggest a solution?
Thank you.
