I have purchased and installed and activated the pro version, it seems like it is not working as when I go to settings in Contact Form 7 there are no extra settings like in the screenshot in the instructions. Please help!
You just need to place the class in the class field when you create the field from Contact Form 7. The snapshot we had was of old version of Contact Form 7. However are not much changes and only need to keep the class in the field.
