I'm new in paypal and I'm not sure how to configure it but I created some test account (seller + buyers).
All seems good. I can make my payment and all infos are correctly sent to paypal. Email address, API username/password and signature are correctly added to the plugin's settings page.
When completed Paypal send me back to the website with an error message : "Oh No, we can't find your Pledge. Sometimes it take a few moments for your Pledge to be logged. You can try refreshing this page "
I go back to my project and there is no pledge recorded. How can I fix this issue ?
