When a customer clicks to pay using the the Square Payments method, no payment window appears. The next page has a "Pay With Card" button which does not link to anything.
Inspector shows these errors:
The resource from “https://squareup.com/v2/paymentform” was blocked due to MIME type (“text/plain”) mismatch (X-Content-Type-Options: nosniff).

Can this be fixed?

Hello,

It seems like you're using and old version of the Square payment plugin, can you download the last version of the plugin through your Hikashop user space and test it again ?

If you're still having that issue, can you send us a temporary back-end access to your website via email at tsukidev.contact[at]gmail[dot]com so that we can directly test and debug it on your website ? Thank you.
