Re: cookie timeout
I had this happen to me. I would imagine that the same thing is happening with you. What my problem was not with the actual integration because it even tells you that you are logged in, but that the ‘URL’ in the config.php file was wrong. I had to really look close at the directions. Using your URL from above I couldn’t make heads or tails because the link wouldn’t resolve, but it most likely is in the following section:
// If your bbPress URL is http://bbpress.example.com/forums/ , the examples would be correct.
// Adjust the domain and path to suit your actual URL.
// Just the domain name; no directories or path. There should be no trailing slash here.
$bb->domain = 'http://yourdirectory.yoursite.com'; // Example: 'http://bbpress.example.com'
// There should be both a leading and trailing slash here. '/' is fine if the site is in root.
$bb->path = '/forum/'; // Example: '/forums/'
Maybe check that out.
