accepts account buttons checkout contact developing disable encrypted pay payment paypal preferences profile screen seller setting site somone store un-encrypted website wonderfully

I am developing a site and have used your buttons for the store. Everything seems to look and work wonderfully, but currently when somone tries to checkout, it goes to a screen that says, "The seller accepts encrypted website payments only. You cannot pay the seller through un-encrypted buttons. Please contact your seller for more details." Does this mean I have to change some setting in Paypal?

That's a setting your need to disable in your PayPal account > Profile > payment preferences.
