Suddenly this morning Amazon searching has stopped working (both in Bookpedia & DVDpedia). I checked my Amazon Associates account and it appears to be fine. I tried to re-register in DVDpedia, but in the Amazon Web Services Settings I got the error:
But when I go and check in Amazon Associate it is registered, though I do see the following message:
Product Advertising API Important Notice
Registration for the Product Advertising API is only available to Associates that have been reviewed and received final acceptance in to the Associates Program. You can request an exception for approval by completing the Contact Us form and providing details about why you require an exception to access PA API. Your request will be reviewed by a specialist and you will receive a response within 3-4 days. If you currently have access to PA API, please ignore this message.
I am running the most recent versions (5.6.1) of the apps.
Please hold down the option key and click on the "Help" menu in the programs. There will be a debug menu, select the "Amazon Test" option if not checked. This will use a new search plugin for Amazon. You only need to do it once.
If you want to use your own keys, there is now a waiting period as the message mentioned, while Amazon decides if they want a new associate. They are limiting the API to bigger associates that produce a certain revenue in links to Amazon.
