 I have a multisite with a few sites set up where I have no problems
 logging in.

 I just added a new domain/site so there are no cookies in my browsers for
 that domain, and I am using the default theme (2014). This is the first
 site I have added since upgrading to 4.0.

 When attempting to login, I get the "Cookies are blocked" error.

 I know the credentials are good, and I have tried with with both firefox
 and internet explorer on separate computers, each browser with extensions
 disabled. I followed the instructions on the firefox page to make sure
 cookies are enabled.

 I disabled all the plugins on my WP multisite (network deactivate) but
 this has not helped. I also temporarily renamed the plugins folder for and
 tested again.

 I am accessing it from a home network with no special proxies to go
 through, and I can confirm that there are plenty of other cookies in my
 firefox browser, some of which are for the other domains in my multisite
 installation for which I remain successfully logged in.

 I have put this up for discussion in the forums, but no one seems to have
 any ideas. https://wordpress.org/support/topic/login-cookie-error-
 multisite

 * I have eliminated the Broswer (or browser extensions) as the source of
 the problem.
 * I have eliminated WP plugins or custom themes as the source.
 * No network conditions such as proxies have prevented any of the other
 domains/sites - from being logged in to.
 * The site front-end shows up in the 2014 theme no problems at all.
