If a network shows "inactive", then your IP address is registered with another OpenDNS user's network. You either obtain another IP addess from your ISP, or you raise a support ticket with OpenDNS to get your IP address released. You can also attempt an update like:
https://updates.opendns.com/nic/update?hostname=NetworkLabel
What you did, deleting the network and creating a new one, was of no use at all. You never should do this.
You know now why the domain is still blocked: you're using another OpenDNS user's settings, not yours.
