Share and Like counts all disappeared -- all zero now.

All social networks tie the share counts to a specific URL. If you've changed the URL for your content, then the share count will not follow to the new URL. There's no way to force the old like count to a new URL. Otherwise, that could be heavily abused by getting users to Like one page and then changing their Like's to an unrelated URL.

We always recommend using either www or non-www for your content so that your share counts are spread between the two variations. The only thing you may want to try now is to use the "Force Scheme" setting in JFBConnect to make all of your share URLs for www or non-www. That may restore your old Like count, but will also cause all shares to use the 'wrong' URL (either www or non-www).

I hope that helps explain, but if you need anything else, please let us know.

Thanks,

The Likes don't just go away. If you know the specific URLs you used to use, you can enter them into the Facebook Debug tool . That can show you the Like count for a specific page so you can find the variant quickly. Even then though, unless you want to go back to that old URL completely, the only option is to setup the share buttons to share the old URL and do a redirect to the new URL. That should show the right count, but will also promote the incorrect URL.

I hope that helps, but if you need anything else, just let us know.

Thanks,
