Why am I seeing a "widget does not exist" message?

There are two reasons why this may happen when pushing data onto Geckoboard:

1. The widget isn't yet fully created. You can only push to widgets that have been saved. Once you set up the widget, save it using the "Add widget" button.
2.  

   

3. The widget was originally polling and later switched to push. If this is the case, delete the widget and create a new push one from scratch.
