Cannot login to multisite

Not sure what happened but I was on last week and updated everything. Now I cannot login. But all the sites are up publicly. But administration is inaccessible. I get to the login page, login and then get "The rescueonedog.com page isn’t working rescueonedog.com is currently unable to handle this request." I got someone to look into it and found that it looks like the Domain mapping plugin. Not sure what to do. See attached log that identifies Domain mapping.
