    I am trying to set up a network, but after inserting the code in the wp-config.php file I star getting the foloowing messages:

    Warning: array_key_exists() [function.array-key-exists]: The second argument should be either an array or an object in /home/rperezq/public_html/wp-includes/theme.php on line 499

    Warning: Cannot modify header information - headers already sent by (output started at /home/rperezq/public_html/wp-includes/theme.php:499) in /home/rperezq/public_html/wp-includes/pluggable.php on line 934

    I changed the active theme to the default WP, but the messages persist.

    Could you please support me with this issue?

    I also installed the Enable Multi-Site Pluggin. The only thing I have not done is changing the Apache Settings as outined in:

    Thanks again,

    P.S. You may notice that if you click my webpage, the error message appears above.

  3. Did you turn off all your plugins before turning on MultiSite?

    Ipstenu, thanks for your kind support.

    I turned some of them off. What should I do now?


  5. All of them. Turn them all off. Every last one.

    Shall I install the WP default theme and uninstall the third party themes also?

  7. You don't have to uninstall, just deactivate.

    I've done everything exactly as instructed in the http://codex.wordpress.org/Create_A_Network webpage and the messages persist.

    I deactivated everything.

  9. Where did you insert the code in your wp-config file?

    Do you have blank lines or spaces at the top or end of your wp-config.php file? That is OUTSIDE the line that are <?php and ?> at the top or end?

    This is where I inserted the code:

    define ('WPLANG', 'es_ES');

    * Para desarrolladores: modo debug de WordPress.
    * Cambia esto a true para activar la muestra de avisos durante el desarrollo.
    * Se recomienda encarecidamente a los desarrolladores de temas y plugins que usen WP_DEBUG
    * en sus entornos de desarrollo.
    define('WP_DEBUG', false);

    define('WP_ALLOW_MULTISITE', true);

    /* INSERTADO POR RobertoPQ

    * define( 'MULTISITE', true );
    * define( 'SUBDOMAIN_INSTALL', true );
    * $base = '/';
    * define( 'DOMAIN_CURRENT_SITE', 'robertoperezq.com' );
    * define( 'PATH_CURRENT_SITE', '/' );
    * define( 'SITE_ID_CURRENT_SITE', 1 );
    * define( 'BLOG_ID_CURRENT_SITE', 1 );

    /* ¬°Eso es todo, deja de editar! Feliz blogging */

    /** WordPress 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');

    It's actually commented out, but I remove the (*) and place the (*/) after the RobertoPQ when I want to activate the multisite back on

    There seems to be a plugin somewhere in your installation that's calling the get_theme() function. For some reason, when it does call the get_theme() function, get_theme() is retrieving something other than an array when it calls the get_themes() function; which is causing the error you're seeing.

    Make sure that, as ipstenu indicated, all of your plugins are disabled. Then, try switching to the TwentyEleven theme. If the error persists, try reinstalling WordPress manually to see if that fixes the issue.

  13. It should look like this. Just to make sure. But what Curtiss said :)

    define('WP_ALLOW_MULTISITE', true);
    define( 'MULTISITE', true );
    define( 'SUBDOMAIN_INSTALL', true );
    $base = '/';
    define( 'DOMAIN_CURRENT_SITE', 'robertoperezq.com' );
    define( 'PATH_CURRENT_SITE', '/' );
    define( 'SITE_ID_CURRENT_SITE', 1 );
    define( 'BLOG_ID_CURRENT_SITE', 1 );

    Hi Curtiss,

    Thanks for your reply. I manually reinstalled WP and apparently it fixed the issue. I'ts working fine now.
