We've been using the amazon-machine-tags (amtap) plugin for almost two years - great plugin, great work by the author.
Today we hit a problem. The sidebar widget and body tag are getting populated with the full XML response from Amazon's API, causing gibberish on the page.
It's like the XSL transform is doing nothing.
We made no changes, so we're assuming this is either a temporary glitch or something caused by Amazon's Product Advertising API changes that have been rolling out this month.
Has any one else seen this problem? Any solutions?
