WordPress MU

All of the sudden my nodblog blog has disappeared. The message comes up "No WPMU site defined on this host."
What do I do? Is my blog just gone?

You need to contact the support folks at nodblog.com as none of us here have access to the backend of that site. A quick Google search for the site shows that sending an email to support [ at ] nodblog [ dot ] com would probably be best.

Good luck
