i just logged into one of my multisites where some sites use this plugin, just to read this message on every dashboard page:
You have no Zemanta API key and the plugin was unable to retrieve one. You can still use Zemanta, but until the new key is successfully obtained you will not be able to customize the widget or remove this warning. You may try to deactivate and activate the plugin again to make it retry to obtain the key.
So how do i get rid of this message?
