cannot complete sandbox payment

Hi,

I set up a new sandbox to test various payments via paypal.

I can enter the subscription, choose item, enter paypal button.
Get redirected to paypal and pay.
Paypal says paid subscrition.
After redirection i get an "invalid" on screen, error log saying fraud attempt and all payments still pending.

What am I doing wrong?

Maybe some german experts here to help?

Please read through your CBSubs Manual and review the parameters within the PayPal gateway carefully to ensure you've configured the PayPal Sandbox business account correctly. PayPal also provides multiple test credit cards of which some of them are designed to always give a failed/denied response for testing so ensure you used the correct test credit card or account.

Finally got it to work, just made wrong settings.

Is it normal that paypal makes 24 hours delay of checking payments?
logged into seller acc. saying working expected until next day.

Another thing, also described as neccessary I cannot activate website encrypting.

ssl is active in settings, everything working fine. Maybe its an issue regarding to my own https certificate of website?

Sometimes, yes, but not typically.

Encrypting the PayPal form is not the same as using SSL on your site. It's also not necessary. Follow the instructions provided in the gateway it self for configuring it if you want to use the PayPal Certificate usage.
