Hello,

Thank you for your feedback !

Can you send us a temporary back-end and FTP access to your website so that we can directly test and debug it ?

You can send it via : tsukidev.contact[at]gmail[dot]com

Thank you.

I've sent you a follow up email with credentials. Thank you!

I would really appreciate an update on this issue. We still can't use Square for payments.
