Re: Cookies login issue with WPMU
I was having the exact same problem, but with normal WP (not WPMU).
My problem was that I instaled wp and bbPress both in subfolders, like:
The problem was on cookies, since bbPress was creating them on root and wordpress both on root and on ./wordpress – but it seems that the ‘good cookie’ was the one on ./wordpress.
This was done by simply adding a line to bb-config.php:
$bb->cookiepath = ‘./wordpress’;
Now it seems that all is working fine.
Hope it helps you too
