User being registered as free subscriber after payment

[Amitps]

Hello,
The S2 Member plugin has been very helpful in what I am trying to do for my site. How ever, I cant find my way around this issue.
I Configured Paypal Sandbox and generated the buttons for "Membership Signup" page.
When I tested as a logged in user, the Membership Level was still of "Free Subscriber" even after the successfull payment.
Same is the case with a Logged in Test User. The membership levels do not seem to be changing even after the payment.
Also, I am getting an error saying-

Unable to verify POST Vars


every time I make a test payment.
I have configured the PayPal® PDT Identity Token settings.
Cant understand where I made a mistake.
Please help

This may be caused by a wrong value for the custom attribute in your shortcode. Could you post here the shortcode for the button you're having trouble with?

Read this too, please viewtopic.php?f=36&t=1066

[Amitps]

Hi,
The shortcodes are-
Button1 -
[s2Member-PayPal-Button level="1" ccaps="" desc="Monthly Subscribers / description and pricing details here." ps="paypal" cc="USD" ns="1" custom="www.rfpbook.0fees.net" ta="0" tp="0" tt="D" ra="5" rp="1" rt="M" rr="0" image="default" output="button" /]

Button 2-
[s2Member-PayPal-Button level="2" ccaps="" desc="Annual Subscriber / description and pricing details here." ps="paypal" cc="USD" ns="1" custom="www.rfpbook.0fees.net" ta="0" tp="0" tt="D" ra="10" rp="3" rt="M" rr="0" image="default" output="button" /]

And now, I generated a single One time payment option for which I generated a code directly from paypal sandbox. The code is-
<form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="TLGV8FPR4XSEW">
<input type="image" src="https://www.sandbox.paypal.com/WEBSCR-640-20110429-1/en_US/i/btn/btn_paynow_SM.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!">
<img alt="" border="0" src="https://www.sandbox.paypal.com/WEBSCR-640-20110429-1/en_US/i/scr/pixel.gif" width="1" height="1">
</form>

Thanks.

And which one was that you had the error with?

[Amitps]

Getting the Same error with all of them.
In fact, I am ready to change my billing model from recurring to One time (the last button), but the error is still there.....

[Cristián Lávaque]

Got it.

Could you please post the IPN log entries for the transactions that gave you trouble?

Thanks.

That's not the IPN log, but it still tells you about the error. It also gives you some instructions, did you follow them?

Thanks Cristian,
Unfortunately, I have no idea about how to run these tests. But I figured it out that my test server does not connect to paypal over HTTPS. I moved to the production server and its working fine.
Now I need to figure out a way to associate EOT with download limit.
I will make a new post for that so that users searching for similar solution can benefit.

[Cristián Lávaque]

I'm glad you solved it! Thanks for reporting back.

Yeah, good idea on starting a new thread for that.
