New Sites can no longer be mapped

For some reason, I am assuming it is due to the updates, I am no longer able to map the URL of a newly added domain. I can add a new site. I can add it in the mapping section, but the URL no longer shows up under the Mapping heading next to the domain. (and it no longer automatically kicks me out of the backend and forces me to then login to the newly added domain.) The newly added domain then resolves to some weird broken version of the primary domain on the account (and nothing at all related to the newly added site). I am assuming this is due to the version upgrades?

My next step, as others on here seem to be suggesting, is to step back to an earlier version of the plugin and see if that resolves the issue. I have tried up to version 0.5.5
