Comment:

 It does not say anything about "headers already sent". The entire error
 is;
 "ERROR: Cookies are blocked or not supported by your browser. You must
 enable cookies to use WordPress."

 I am using the 2014 theme and the error is produced with ALL plugins
 deactivated.

 Nothing shows up in the error log, and the access log looks normal.

 Someone else has posted that they are having the same problem with their
 multisite installation.

 I have set the severity to 'blocker' since one cannot create content for
 the site without it being solved. All one can do is create an empty site -
 which is of course pointless without content.
