I have installed WordPress Amazon Associate. I'm an Amazon affiliate. I also signed up with Amazon Web Services and got my access key and secret key validated. Then, I went to Amazon Affiliates and copied the HTML of a book I want to advertise. (I'm using WordPress.org, so no problem there.) I pasted the code in the HTML view of the page I'm using, and updated the page. I got a yellow box in the visual view of the page, and nothing shows up on the user end of my website. I also tried used the code from the Amazon Quick Links, where you edit the page, but same result. Can anyone help me figure out why it's not showing up? I did have success once, with one book, a few days ago, but I don't know what I did differently and I've deleted that one now. Thanks in advance!
