A few weeks ago, unbeknownst to me, Google made a (wise) change to its APIs to require SSL for all API calls. This caused parts (but not all, apparently) of the Docs to WordPress plugin to stop working.
This evening I released an update to that plugin that should resolve any problems people had. In addition, I made a small change to make bold and italics come through more consistently.
As always, you can download the latest version in the WordPress Plugin Repository.
