 * Hello, I recently migrated my multisite wordpress installation to a new server.
   I use subdomains and have WordPress MU Domain Mapping plugin to handle domain
   redirects.
 * This has worked amazingly in the past (great tool!). However, since I migrated,
   I receive an error when logged in and navigate to the front end site. When not
   logged in, the site works as expected.
 * The page displays the error “Unknown login key”.
 * I have not much luck in finding a solution to this issue.
 * Many thanks in anticipation

 * Try turning off the remote login setting.

 * I experienced this as well and deselecting the remote login worked BUT attempting
   to access the primary domain was redirecting to an ?action=login&dm=5f361d501b7b55e…
   string.
 * So the homepage loads but it includes that redirect for logged in admins. Here
   are the domain settings for this install (lovethistown.org): [https://www.screencast.com/t/euVsPNQAA](https://www.screencast.com/t/euVsPNQAA)
