Reply To: Contact Form 7

Hello,

I have checked your website by activating the default WordPress Theme and the contact form is behaving the same in it as well that means the issue is not with our Theme. Unfortunately, we could not help you with this because this is out of our scope.

You can try contacting contact form 7 plugin support for further help.
