Latest Domain Mapping Plugin Loop error

When using previous version of this plugin, login and logout works seamlessly. When installing latest .1 version of plugin I get the following message when logging in/out of network dashboard. I've gone back to previous version until fix is identified. Please advise, Thanks

Please wait...
