Square Integration: Square Payment Form can only be embedded on sites that use HTTPS

I have been trying to install a membership form on our website but now that I added the Square portion, I am getting this error:

Square Payment Form can only be embedded on sites that use HTTPS. See: https://docs.connect.squareup.com/articles/adding-payment-form/ Please contact form administrator.

If you embed your form on non-https website, try to use an iFrame form code.

Getting the form iFrame code

Please give it a try and let us know if you need any further assistance.
