API error

[vezguer]

Hello,

I'm new to s2member forum, thank you for your great plugin.

I'm building a VOD site, and i'm using s2 for selling specifics posts. I'm currently testing it with paypal sandbox, and sometime when i return to my site after a payement i've got the dreaded error "ERROR: Unable to verify $_POST vars."

i follow the link (Ideal Server Configuration for s2Member) and check if my server is well configured. It is. I also check my paypal option in s2member config...

I've noticed a glitch in wordpress, sometime when i install a plugin i've got an message (HTTP error on API). If i retry it's work. maybe there is a connexion...

i'm young, i'm innocent, please help

Could you please post, x'ing out any private info, the log entries related to that problem you're having? WP Admin -> s2Member -> PayPal Options -> Account Details -> Enable Logging

Hello Cristián,

i think i found a solution : i installed the core control plugin and i deactivated the use_curl_transport option. now wordpress is using fsockopen transport only and it's working.

I'm not a specialist, so maybe you can comment my solution.

Thank you for your quick answer, i will come back if there another problem.

Cool, I hope that fixes it for good and you don't have any more trouble with it.
