Hi, I am not sure if this is related but for the last few days I can't accept paypal payments. It takes the buyer to paypal and then back to our website to pay.
Any suggestions please? Paypal said it is not happening on their end.
I ran the test in the backend and it says I am connecting so can't figure it out.
What does this mean please - Duplicate entry '2754' for key 'PRIMARY' ?
Thank you
