Having just updated my WP install, Mailchimp Campaign Archive doesn't seem to be working any more (was fine previously, and using it successfully on various other sites). I'm using this code:
[mailchimp_campaigns apikey="xxx" limit="100" order="DESC" link_text="subject" status="sent" list_id="828bb9c692"]
...where xxx is my API. I generated a new API just in case but it didn't help.
The page is here, the archive should appear under the heading. No error.
