[Plugin: Gravatar Hovercards] [FIXED] Hovercards don't Appear

The problem is simple – With this plugin enabled, and a working Gravatar, it won’t show the profile. It does the little tilt animation, but the gravatar doesn’t appear.

The problem is that the email used is not the primary one and the Gravatar API will not pass along the profile for sub-emails. The problem isn’t with the plugin.

The work-around is to make active the email you want to show the profile for.

Cheers, Sean.
