    Hi folks,

    I knooooow many before me have had, asked about and gotten answers to this issue ..but some are for older versions of WP, and I JUST can't get this to work :-(

    Situation: I have two *different installs (WP1 and WP2)of WP on the same domain running on the same database using different prefixes.
    *different = WP2 is a backupbuddy backup of WP1.

    Need: To be able to login ONCE on eiter WP1 or WP2 and to then be logged into both.

    Problem: I have tried "everything", but I just can't get it to work! Salts are the same in wp-config.php for WP1 and WP2.

    This is the wp-config.php of WP2. Values are changed to dummy values:

     * The base configurations of the WordPress.
     * This file has the following configurations: MySQL settings, Table Prefix,
     * Secret Keys, WordPress Language, and ABSPATH. You can find more information
     * by visiting {@link http://codex.wordpress.org/Editing_wp-config.php Editing
     * wp-config.php} Codex page. You can get the MySQL settings from your web host.
     * This file is used by the wp-config.php creation script during the
     * installation. You don't have to use the web site, you can just copy this file
     * to "wp-config.php" and fill in the values.
     * @package WordPress
    // ** MySQL settings - You can get this info from your web host ** //
    /** The name of the database for WordPress */
    define('DB_NAME', 'wp_db');
    /** MySQL database username */
    define('DB_USER', 'wp_user');
    /** MySQL database password */
    define('DB_PASSWORD', 'password');
    /** MySQL hostname */
    define('DB_HOST', 'something.unoeuro.com:');
    /** Database Charset to use in creating database tables. */
    define('DB_CHARSET', 'utf8');
    /** The Database Collate type. Don't change this if in doubt. */
    define('DB_COLLATE', '');
     * Authentication Unique Keys and Salts.
     * Change these to different unique phrases!
     * You can generate these using the {@link https://api.wordpress.org/secret-key/1.1/salt/ WordPress.org secret-key service}
     * You can change these at any point in time to invalidate all existing cookies. This will force all users to have to log in again.
     * @since 2.6.0
    define('AUTH_KEY',         'salt1');
    define('SECURE_AUTH_KEY',  'salt2');
    define('LOGGED_IN_KEY',    'salt3');
    define('NONCE_KEY',        'salt4');
    define('AUTH_SALT',        'salt5');
    define('SECURE_AUTH_SALT', 'salt6');
    define('LOGGED_IN_SALT',   'salt7');
    define('NONCE_SALT',       'salt8');
     * WordPress Database Table prefix.
     * You can have multiple installations in one database if you give each a unique
     * prefix. Only numbers, letters, and underscores please!
    $table_prefix  = 'wp1_';
     * WordPress Localized Language, defaults to English.
     * Change this to localize WordPress. A corresponding MO file for the chosen
     * language must be installed to wp-content/languages. For example, install
     * de_DE.mo to wp-content/languages and set WPLANG to 'de_DE' to enable German
     * language support.
    define ('WPLANG', 'da_DK');
     * For developers: WordPress debugging mode.
     * Change this to true to enable the display of notices during development.
     * It is strongly recommended that plugin and theme developers use WP_DEBUG
     * in their development environments.
    define('WP_DEBUG', false);
    $root_host = 'mysite.com';
    define( 'COOKIE_DOMAIN', '.'.$root_host );
    define( 'COOKIEHASH', md5('http://'.$root_host) );
    /* That's all, stop editing! Happy blogging. */
    /** Absolute path to the WordPress directory. */
    if ( !defined('ABSPATH') )
    	define('ABSPATH', dirname(__FILE__) . '/');
    /** Sets up WordPress vars and included files. */
    require_once(ABSPATH . 'wp-settings.php');

    I've alto tried:

    $cookiehash = md5("http://uniqture.dk");  // Use Site A's URL
    define(CUSTOM_USER_TABLE,'uniqture_users');           //Change 'wp' to match the prefix set during
    define(CUSTOM_USER_META_TABLE,'uniqture_usermeta');   //  Site A's installation
    define('COOKIEPATH', '/');                      //This path should reference Site A's root
    define('SITECOOKIEPATH', '/');                  //Should match 'COOKIEPATH'
    define('COOKIEHASH', $cookiehash );

    Can anyone help me getting this t work? It's probably simple as heck ..but I just can't get this important "little" thing to do as I want it to :-(

    (..and no, a multisite is not a solution for me, as I need an exact copy of my main site, whis will take me forever to recreate + need 100% control when editing both sites)

    Thanks a lot in advance for any help! :-)

    [ No bumping please. ]

    I got the exact same problem here, and I've been searching all along solutions but nothing I find on the web seems to work for me, may be because is done for older versions of WP as kalledrengennr1 says.

    Can anyone help me?

    Thanks so much!
