I tried putting in my Amazon security credentials and affiliate id but whenever I search for products it gives me this message:
Your AccessKey Id is not registered for Product Advertising API. Please use the AccessKey Id obtained after registering at https://affiliate-program.amazon.com...i/sign-in.html
When I searched the forums, I found this thread and did what Eric suggested and I keep on getting the same results.
I even tried the scratchpad thing and got the same as above thread screenshot. The thread suggests thing but it doesn't state how it was resolved.
Note I didn't place my security credentials in my WP site yet.
Appreciating the help.
