Custom Dashboard Plugin code error

Hi there i'm having problems with the Custom Dashboard Widget, i've network activated it but on the sites it's appearing with code error:

Only if i login as admin on sites can i configure the widget on the dashboard itself, but i need the message to be customised from the Network Site home.

Also is there anyway of getting this plugin or another to show on the Easy blogging Dashboard? There are 2 sections in the Easy Blogging that are blank and would be good to use.
