S2member redirect 302 from paypal

#1

After returning from Paypal (using IPN) instead of properly continue the registration I get multiple 302 until the page collapse with “Too many redirections”.

This is the return link (with some editing of course):
https://www.xxx.com/?s2member_paypal_return=1&s2member_paypal_return_tra=xxx&amt=xxx&cc=xxx&cm=xxx&item_name=xxx&item_number=xxx&st=xxx&tx=xxx&do_not_cache=28406

How can I fix it?

I tried to take a look at the debug (log) files I have paypal-api.log, nothing jump to the eye there.

Please help me.

Hi!

Could you verify that your s2-paypal integration is complete and correct? Are you using the s2 shortcode for paypal buttons, or is it some other code? Can I see it?

Also the core-rtn log entries for your test with the issue, please. WP Admin > s2Member > Log Files

Thanks. :slight_smile:

I use s2member shortCode here it is:

[s2Member-PayPal-Button level="1" ccaps="" desc="XXXXXXX" ps="paypal" lc="" cc="ILS" dg="0" ns="1" custom="https://XXXXX" ta="0" tp="0" tt="D" ra="360" rp="1" rt="Y" rr="BN" rrt="" rra="1" image="default" output="button" /]

The log:

Thanks for the new details.

First thing I notice is the https:// in the custom value. It should just be the domain name (with the subdomain if you use one, e.g. “www”). So it’d be “mysite.com”, not “https://mysite.com”. The s2 button shortcode generator should give you the correct value for the custom attribute.

Could you fix that in the shortcode, reload the page with it, and try a new test?

I look forward to your update. :slight_smile:
