Conflict issue with Contact Form 7

Hey @lucaminici

If it’s only happening with forms that were created with Contact Form 7 (and you don’t see this issue with other forms, such as the standard WordPress contact forms, or the WooCommerce checkout page), it’s best to reach out to Contact Forms 7 directly.

Third party plugins are best supported by their own resp. developers (and more importantly, I’d rather not give you any incorrect information).

You can reach them here:

Thank you, I moved the question in wpcf7 support and found a temporary solution.
