Paypal Standard Issue

I just used Paypal Standard as a payment plugin, I recreated my NVP/SOAP-API User, Password, Signature on the Paypal side and put it to the payment plugin. 

If I checkout something and like to pay via PayPal I get always an redirection to Paypal with the error message  "Unfortunately, a system error has occurred. Try again later"
Wenn I use sandbox account everything works like a charm.

Ok I found out some more informations. Paypal gives me an EWP_SETTINGS issue. That is because I hat the settings in PayPal to block unencrypted payments. In the PayPal technical help community I found the following 

By default, you accept payments from encrypted and unencrypted buttons. For additional security, you can prevent buyers from sending payments to you through unencrypted buttons.
After you change this setting, we reject payments from your buyers who click an unencrypted Buy Now button, an unencrypted Donation button, or an unencrypted Subscription button. This is when you see EWP_SETTINGS error message.If you previously blocked payments from unencrypted buttons, here’s how to accept all payments:

1. Log in to your PayPal account.
2. Click the Business Profile icon beside "Log Out" and select Profile and settings.
3. Click My Selling tools.
4. Click Update near 'Website preferences.'
5. Select ‘Off’ next to ‘Block Non-encrypted Website Payment

Once you turn off this setting you will no longer receive the error message. 

That works as a workaround for me at the moment. Question here is... why does the plugin send the payment data unencrypted?

Hello Robert

I don't really understand this unencrypted payment issue. It's PayPal Website Payment Standard specification, nothing special. It has been used for years without any problem

If you worry about this, you can contact PayPal and ask them more details about it. But this PayPal Website Payment Standard is widely used, so I don't see any issue here

Yes like I wrote: it is working when I allow unencrypted communication on PayPal side. So I think the request from the plug-in to PayPal is done wit http instead of https. But let’s see what PayPal responses 

It always uses https to transfer data to PayPal, so I guess it is something else (You can view source of the page to view the URL which we submit form data to PayPal, it is www.paypal.com/cgi-bin/webscr (so it's https URL)
