Multisite user roles

Hello Guys,

Having a bit of an issue with user roles on my Multisite BuddyPress website

When a user creates their own blog - they cant login to dashboard as the message says

"You do not have sufficient permissions to access this page"

Also when you hover over My Sites in Admin bar all the network blogs are displayed?
Again they cannot access their Dashboards but just seems a bit odd.. (See ScreenShot)

I am looking for an easy way to manage user roles (Plugin) and any advice on best practice for this would be great..

Kind Regards

James
