ERROR: Cookies are blocked or not supported by your browser (5 posts)

    I have been asked by a friend to revamp their WordPress multisite which someone else created for them a long time ago. I signed in to the account and firstly updated it to WP 3.6. Since then every time I try and log in at the normal site address /wp-login.php which the original designer gave them I get the following error message "ERROR: Cookies are blocked or not supported by your browser. You must enable cookies to use WordPress".

    I have tried clearing all cookies, history etc. on multiple browsers which hasn't done anything.

    I have also tried logging in at the site address /wp-admin/ and get this message:

    Warning: Cannot modify header information - headers already sent by (output started at /home/content/64/9421064/html/wp-content/plugins/twitter/widget_twitter_vjck.php:171) in /home/content/64/9421064/html/wp-includes/pluggable.php on line 896

    I only have access to the WordPress account and non of the original source files.

    Any help would be much appreciated!

    My guess is that twitter plugin is not compatible with WP 3.6. I would disable or remove the plugin.

    Had the same issue and I added this to my wp-config.php which fixed it:

    define('ADMIN_COOKIE_PATH', '/');
    define('COOKIE_DOMAIN', '');
    define('COOKIEPATH', '');
    define('SITECOOKIEPATH', '');

    Thanks for the tips, jkhongusc I can't actually get into the wordpress dashboard though to disable any plugins.

    Also Dave Navarro JR is there a way to get in to the config without signing in or having any of the files attached to your computer? I have literally been given their wordpress username and password to work with.


  5. Nope :/

    You also should check for blank lines below the ?> at the end of the wp-config.php file.
