PayPal Payment Module Error


Recommended Posts

I get an error from Prestashop in multiple languages concerning the PayPal payment api:

 

Not a valid cart

Not a valid currency

 

This happens numerous times throughout the day, but there is no order. Any ideas? Thanks in Advance!

Is there an error number to reference it with? Also look at your server logs, and see who is generating the error. I remember something a while ago about people trying to inject their credentials into a paypal attack like that. It was on another platform, though, NOT prestashop.

You should check you server logs and match up the time that these are happening. The reason I suggest this, unless I am wrong, this can happen by spidering. If someone directly accesses you paypal link by-passing your cart it will generate a similar error. So you should see if baidu or googlebot or yandex or someone is spidering your site when this happens.
