WordPress MU

Hi, I've just upgrade my wpmu to 2.7 and after that, my members can't log in to their blog's admin.

On the other hand, some of them are able to login to admin page of the root/main blog.

I've tried to login from the backend to user's blog admin and was unable to login too as the "administrator".

Anyone here know what has went wrong? Please help. Thanks!

ok. found the solutiom.
adding the following lines to config file solved the problem:

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

:)

Hmmm... so I just had to do this, too. Why?

And is there any security issue with just having done this?

Because they changed the code so it was required. It stores more cookies to be *more* secure than before the upgrade.

Ah, interesting. Thanks, Andrea, for the update.

I've now edited the WPMU Upgrade instructions in the Codex to reflect this.

Thanks

Awesome. :)

Brilliant.. thanks andrea_r :) m.
