Hello,
I have the same problem. With the extension “Fetch book cover” enabled the “Fetch”-button next to the Cover field (in the sidebar) does not appear at all. In htlm page code I read input hidden type tag, but value attribute is null. I read rcno-fetch-book-cover file and get_post_meta function doesn’t seem to work.
Fetch button next to ISBN field appears and works, but doesn’t get description.
Thanks
