 * Since updating WP yesterday, When users attempt to login to my WP site, they 
   receive an error message:
 * “Cookies are blocked or not supported by your browser. You must enable cookies
   to use WordPress.”
 * Cookies are enabled, and if you re-enter your login information on the same page
   with the error, you can access the site without difficulty. You will then never
   see the message if you logout and login , unless you clear your cookies, then
   it returns.
 * Never had the message before, and with cookies enabled in all browsers, you still
   see the message the first time logging in.
 * Any one else experiencing this or have a suggested solution? All help is appreciated!

 * Have you tried:
    – deactivating ALL plugins temporarily to see if this resolves
   the problem. If this works, re-activate them individually (one-by-one) to find
   the problematic plugin(s). If you can’t get into your admin dashboard, try deactivating
   via [FTP or SFTP ](http://codex.wordpress.org/FTP_Clients)or whatever file management
   application your host provides. If applicable, also remember to deactivate any
   plugins in the mu-plugins folder. The easiest way is to rename that folder to
   mu-plugins-old. – To rule out any theme-specific issue, try switching to the 
   unedited default, core-bundled Theme (such as Twenty Twelve or Twenty Thirteen)
   for a moment using the WP dashboard. If you don’t have access to your admin area,
   you can switch to the default theme by renaming your current theme’s folder in
   wp-content/themes and adding “-old” to the end of the folder name using via FTP
   or SFTP or whatever file management application your host provides. Alternately,
   you can remove other themes except the default theme. That will force your site
   to use it. – [resetting the plugins folder](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)
   by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause
   problems (because the hooks remain unless plugins completely removed or some 
   plugins stick around in cached files. So by renaming the folder, you break them
   and force them inactive).

 * I’m now having exactly the same issues; a site that was working perfectly prior
   to the update now issues the “Error: Cookies are disabled or…” message whenever*
   anyone* tries to log on. nothing on the site was changed other than the WP 3.7.1
   update; This issue is cross-browser.
 * I’ve disabled all plugins and switched to a stock twenty twelve theme to no avail.
   I’ve cleared Cache & cookies on each browser I’ve tried (IE, Firefox, Chrome,
   Safari…)
 * Apparently as part of the new update login.php is now issuing a test cookie that
   is not being properly read on the first pass. If you reenter the username and
   pw on the error screen, you will be successfully logged in, but far to many users
   are not giving it a second try…
 * So, basically, this nifty new update has tanked my – and a great many other users–
   ability to have people log on to their WordPress sites.
 * Any ideas how to fix this?

 * Seeing the same issue here on multiple 3.7.1 sites. Trying to log in a second
   time works properly.

 * Have you guys discussed this issue with your respective webhost?

 * It is apparently a login update with WordPress. An “improved” control mechanism
   during the login process to check if a browser can store cookies. This cookie,
   however, is only set in the wp-login.php file and in many login scenarios, the
   cookie is set too late to be of any real use.
 * Luckily for me, my membership plugin provided an update to work around the issue.
   As for solving directly, I unfortunately can’t provide much assistance but hope
   this information helps!

 * * I use OVH hosting more than 6 month and there is no change in hosting setting.
   My site worked until last update 3.7.1 .
 * * I change wordpress : 3.7.1 to 3.7 and 3.61
    I remove all plugin folder to deactivate
   all of them I used default 2013 & 2012 theme I change browser too : chrome & 
   IE & fierfox & opera but none of above solution work to solve this problem .

 * I have discussed it with my web host. Fairly easy because I am my web host.
 * While I do apprciate suggestions such as “check with your web host,” please keep
   in mind that this isn’t an install or plugin issue, but a problem created by 
   the core code being the only thing modified, causing the previously working install
   to fail.
 * It’s a matter of us needing to know *what* to talk about to our web host (or 
   ouselves in my own case) in order for us to fix a problem someone else made for
   us.

 * I encountered the same issue and have managed to make it work, and a theory of
   what could be the issue.
 * First of all, how to get logged in again. Comment out lines 744-746 in wp-login.
   php . It should look like this:
 *     ```
       //	if ( isset($_POST['testcookie']) && empty($_COOKIE[TEST_COOKIE]) )
       //		$user = new WP_Error('test_cookie', __("<strong>ERROR</strong>: Cookies are blocked or not supported by your browser. You must <a href='http://www.google.com/cookies.html'>enable cookies</a> to use WordPress."));
       //	else
       		$user = wp_signon('', $secure_cookie);
       ```
   
 * This will bypass the check entirely and logs you in.
 * At first I didn’t understand why it might fail, but then I remembered I am running
   behind a Varnish cache which filters out all but some select cookies. I haven’t
   checked, but I am fairly certain that my Varnish setup filters out the WordPress
   test cookie when it receives the login request (the actual POST with the login
   data). Is it possible all of you are running behind a proxy which filters cookies?
 * This is pretty sloppy by the WordPress team. They could also just test the session
   cookie. If THAT one doesn’t get through, it will fail anyway. Completely breaking
   when a test cookie is missing should not happen.
 * I hope this helps…

 * Would it help to use wp-login.php from a previous version? Probably not, because
   I understand from your post that the real problem is somewhere else in WordPress’s
   code?
