The reviews iframe widget has stopped working in the last week. Iframe HTML is obtained from the XML API (/book/show/{BOOK_ID}.xml?key=XXXX). The HTML is located at "book.reviews_widget" in the response data. The HTML itself isn't missing, but nothing visible is rendering in the iframe. (There is some content inside the iframe but it looks like it's just Twitter scripts.)
On Firefox, it's giving the following network error: "Invalid X-Frame-Options header was found when loading “https://www.goodreads.com/api/reviews... “ALLOWALL” is not a valid directive." (This error doesn't show up on Chrome, although the iframe fails on any browser.)
The "?did=DEVELOPER_ID" in the iframe URL looks weird, might be a clue.

Any help would be much appreciated.
