Today, I've just updated the Comments plugin, now based on href property, after changes introduced by "July 2013 Breaking Changes".
Using the new href-plugin I no longer see the xid-comments, but I can see new posted comments.
I've read and followed the trick explained here but nothing changed.
I've made some tests on my own and these are the results:
Using the new plugin I get only the comments with href property;
<fb:comments href="http://www.mywebsite.com/post/2"></fb:comments>
If I revert the new plugin with the old one (I mean fb:comments with xid property) I get back my old comments, but not the href-posted comments;
<fb:comments xid="2" url="http://www.mywebsite.com/post/2"></fb:comments>
If I force to send xid and href properties together in fb:comments, by manually changing the plugin, I got only the new comments;
<fb:comments xid="2" href="http://www.mywebsite.com/post/2"></fb:comments>
Even If I add migrated=1 in these cases, the results are as described previously.
Of course I've both xid and href values related to a page.
Is there a way to "import" the xid-comments into the href-comments, or to get all comments together?
Sadly, it is not possible to merge comments from an XID to an href.
