Domain Mapping not working on recent updates

Got this error on browser address bar: http://zcada.net/?__domainmap_action=domainmap-authorize-user&auth=admin|1414398893|45UeLZZcFbEOzcAbDTb1cwcrF0CaFokkgT1mHA2hFhD|db8159db3ad760afb3d1eb0a61b8fa150ac4f28bc23544010a8b61779f28603d

The domain was working until recent DM update. I tried delete and re-add domain with no luck.

Please advise.
