A profile may not be LIVE due to various reasons. Upon logging onto the dashboard with your registered email id, the system would display the reason and the next course of action that needs to be taken to move the profile to LIVE status.
In the example image below, the profile is not LIVE due to Upgrade Required. All that needs to be done to re-activate the profile is either click on "Upgrade and Send Proposal" or click on "Edit" and follow the onscreen instructions.
