Yesterday I found my users of an WMPU system can’t login from Internet Explorer. So I search for a solution and find one who work for my clients.

Solution are pretty simple and all you need is to make some modification on wp-config.php files.

You must add some new lines of codes written bellow:

define(‘ADMIN_COOKIE_PATH’, ‘/’);
define(‘COOKIE_DOMAIN’, ”);
define(‘COOKIEPATH’, ”);
define(‘SITECOOKIEPATH’, ”);

This problem don’t appear in Firefox or Opera, so if you want your users to use only Firefox or Opera you may ignore this changes.
