Hello, I am having the same issue. I am using th WP Full Stripe Plugin with this one. I am told that this HTTPS plugin I am using is actually re-writing the code from WP Full Stripe to the non secure version on pages you designate non-https. Full Stripe ALWAYS uses the secure version.
So, I am getting the same mesage js.stripe.com must be accessed via SSL on my non https pages. “Try changing your script tag to: <script src=”https://js.stripe.com/v2/”></script>” when using mobile browswers.
Any devs have a workaround on this?! Thank You.
