Comment (by michaelconroy):

 I've got the same issue. I'm locked out of my WP dashboard. Message on
 login box says "ERROR: Cookies are blocked due to unexpected output. For
 help, please see this documentation or try the support forums."

 I've followed the recommendations above with no success:-

 1. I've individually renamed all the various plugin folders and reloaded
 the WP login page
 2. Via ftp I've reinstalled the functions.php file for the active theme
 3. I've opened the wp-config.php file and reloaded it ensuring that it's
 been saved in UTF-8 format.

 I've requested access to the log filed from my hosting provider. I'm
 hoping this might identify the problem file.

 Any other suggestions?

 What is my solution if the source of the error remains unfound?

 Thanks

 Mike
