Error with Buy Now Button

I am trying to use the Buy Now button to 1) have a member pay for a luncheon and 2) set a ccap to

Here is my code:

[s2Member-PayPal-Button level="*" ccaps="2013_annual_luncheon" desc="Corporate Table at 2013 Annual Lunchean" success="http://asmda.us/thank-you/" ps="paypal" lc="" cc="USD" dg="0" ns="1" custom="asmda.us" ra="0.01" rp="1" rt="L" rr="BN" image="default" output="button" /]

I am getting this error.

ERROR: Unable to verify $_POST vars.
Please contact Support for assistance.

Any ideas why?

I can successfully use PayPal to pay for membership levels I have setup.

Hi Bill.

Could you copy this PHP script to your WP directory and load it in your browser? Does it show any errors/warnings? http://www.s2member.com/r/server-check-tool/

I ran the Check Tool and it showed no errors. Now what?

Also, I am not getting email notifications of replies to me forum posts, any ideas?

Thanks,
Bill

Okay.

Did you verify that all your PayPal integration is done correctly and doesn’t have any errors? It seems that way, since you can complete some transactions…

Also, make sure you have logging enabled and run a test transaction that causes this error, so we get those logged and can look at the entries, please. [hilite path]Dashboard -› s2Member® -› PayPal® Options -› Account Details -› Logging[/hilite]

Thanks!
