Problem with Domain Mapping plugin

I can no longer log into the console wordpress because it is always redirecting to the login page.

I made a simple installation of wordpress multisite in (using subdirectories rather than subdomains) and am just with WPMUDEV Dashboard installed.

Before you install and enable the plugins you can get in and out of wordpress island without any problem.

When you enable it, step by not getting access to the administrative panel, says that the username and password are invalid.

I've done several attempts, but it still fails.

Need help.
