Era Varnish.

Ilnostro host web aveva Varnish configuratoin modo specificoper Drupale stavafiltrandoi cookie che WordPress utilizzapergestiregli accessi.

It was Varnish.

Our web host had Varnish set up in a Drupal-specific manner, and it was filtering out the cookies that WordPress uses to handle logins.

Aggiungi la riga sottostante altuo wp-config.phpprima di/* Questo ètutto,smetti dimodificare! ... */

  define('COOKIE_DOMAIN', $_SERVER['HTTP_HOST'] );

/* That's all, stop editing! Happy blogging. */
 

Add below line to your wp-config.php before /* That's all, stop editing!...*/

 define('COOKIE_DOMAIN', $_SERVER['HTTP_HOST'] );

/* That's all, stop editing! Happy blogging. */

Sono stato cercato su Google & amp;provatotuttii modiper sbarazzarsi di questoproblema coni cookie. Finalmente hotrovato due soluzioni chepotrebbero aiutarti.

Soluzione 1:

yoursite/wp-login.php

Commenta le righe 770-773

Codice

 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);
 

Potrebbefunzionareper alcuni siti webe alcuni sitipotrebberomostrare unapagina vuota. Inoltre,questonon è consigliato,poiché questofilepotrebbeessere sovrascritto dopo l'aggiornamento di wordpress,quindiprova una seconda soluzione.

Soluzione 2:

yoursite/wp-content/themes/yourthemeFolder/functions.php

Inserisciil seguente codice.

  setcookie(TEST_COOKIE, 'WP Cookie check', 0, COOKIEPATH, COOKIE_DOMAIN);
if ( SITECOOKIEPATH != COOKIEPATH )
    setcookie(TEST_COOKIE, 'WP Cookie check', 0, SITECOOKIEPATH, COOKIE_DOMAIN);
 

Anche l'aggiornamento deltuotemapotrebbeperdere questemodifiche,quindiperfavoreinserisci questo codicein un altrofunctions.php,che sitrova sotto la cartella deltemafiglioneltuotema attivo corrente. Spero,questoti aiuterà.

I have been googled & tried all ways to get rid of this cookie issue. Finally i found two solutions, which could help you.

Solution 1:

yoursite/wp-login.php

Comment following lines 770-773

Code

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);

It might work for some websites and some sites may show blank page. Moreover, this is not recommended,as this file may be overridden after wordpress update so try for second solution.

Solution 2:

yoursite/wp-content/themes/yourthemeFolder/functions.php

Place following code.

 setcookie(TEST_COOKIE, 'WP Cookie check', 0, COOKIEPATH, COOKIE_DOMAIN);
if ( SITECOOKIEPATH != COOKIEPATH )
    setcookie(TEST_COOKIE, 'WP Cookie check', 0, SITECOOKIEPATH, COOKIE_DOMAIN);

Updating of your theme may also loose these changes so please place this code in another functions.php, which is under your child-theme folder in your current active theme. Hope, this will help you.

Ho avuto anche questoproblema di recente,si è scoperto che sebbeneilnome di dominiofossepuntato versoil sito Web,il sitomultiplo di wordpressnon aveva un recordnel databasepermappareilnome di dominio alblog corretto,quindi quando wordpresseracercando diimpostarei cookie,stavaimpostandoil cookieperil sottodominioinvece del dominiomappato.

I also had this issue recently, it turned out that although the domain name was pointed towards the website, the wordpress multisite didn't have a record in the database to map the domain name to the correct blog, so when wordpress was trying to set the cookies, it was setting the cookie for the subdomain instead of the mapped domain.

Hoimplementato la soluzionefornita da wpdevramkie honotato chepotrebbeemergereil seguenteproblema:

"Avviso: costante COOKIE_DOMAINgià definitain/wp-config.php alla riga 102"

Per risolvere questoproblema,commentail codice seguentenelfile wp-includes/default-contants.php

 if ( !defined('COOKIE_DOMAIN') )
    define('COOKIE_DOMAIN', false);
 

I implemented the solution given by wpdevramki and noticed that following issue might surface:

"Notice: Constant COOKIE_DOMAIN already defined in /wp-config.php on line 102"

To resolve this, please comment out the following code in the wp-includes/default-contants.php

if ( !defined('COOKIE_DOMAIN') )
    define('COOKIE_DOMAIN', false);
