ERROR: Unable to verify $_POST vars.

I am totally stumped with this error. I ran the s2-server-scanner.php and it came back with no problems.

I have read through tons of the posts regarding this issue and I deactivated every plugin except S2Member, I have logs turned on, I verified that my custom setting in the paypal button is correct etc…..and nothing works.

Here is my shortcode: [s2Member-PayPal-Button level="7" ccaps="" desc="Temporary Member / description and pricing details here." ps="paypal" lc="" cc="USD" dg="0" ns="1" custom="www.aocpmr.org" ta="0" tp="0" tt="D" ra="0.01" rp="1" rt="D" rr="BN" rrt="" rra="1" image="default" output="button" /]

My website url is http://www.aocpmr.org

Please help :)

Thanks

On your installation this error is caused by an invalid PDT Identity Token.
