  • I managed to install WordPress on multiple domains using advanced options in wp-config.php.

    Now, I want users who are logged in at somedomain.com to be logged in at theotherdomain.com.

    In older versions of WordPress, this can be done by merely defining USER_COOKIE and PASS_COOKIE in wp-config.php. However, now there is another cookie item which is PHPSESSID and values vary for user on somedomain.com and theotherdomain.com.

    How can I, at least, make the PHPSESSID value the same for a single user accessing both different domain or would anyone tell me how it is constructed?

    Thanks.
