Undefined index: path, VW kicking users

Hello!

Since the newest upgrade, I've been getting these server errors:

Code:

ErrorException: Undefined index: path - library/vw/XenForo/Route/Prefix/vw.php:67
Stack Trace

  }
  ["_POST"] => array(0) {

}

  }
  ["_POST"] => array(0) {

}

Some users have also been logged out of their accounts while accessing the wiki. They have told me that they have enabled cookies as is prompted in the message that comes up, but that this has not resolved the problem.

In library/vw/Route/Prefix/vw.php, find:

Code:

if (vw_Hard_Core::model('URL')->paths_equal($base_path['path'], $requestUri))

Before it, add:

Code:

if (empty($base_path['path'])) { $base_path['path'] = ''; }

These errors occur when the wiki is located on a separate (sub)domain from the forum and the wiki path name is blank. If you did not intend for the wiki to be on a separate subdomain, please check your settings in AdminCP > Home > Options > VaultWiki: Site Config > Wiki Base URL.

If the subdomain difference is intended, see below:

Regarding users getting logged out, this is normal if the wiki is not on the same domain that the user logged in on, due to browser security (sometimes even www.mysite vs mysite). In order to avoid this issue:

If the wiki and forum are subdomains of the same domain, then you should reduce the strictness of your cookie domain in library/config.php:

Code:

$config['cookie'] = array( 'path' => '/', 'domain' => 'mysite.com' );

If the wiki is on a separate domain entirely, at the current time, you would need to use a multi-site add-on such as XenCentral, which should allow you to manage logins for multiple sites that use the same user database. We are not affiliated with XenCentral, but it is the only add-on I know offhand that provides cross-domain logins at this time. However, I agree that VaultWiki should provide the multi-site login itself if the wiki is configured on a separate domain from the forum, and this issue should be fixed. So I do not recommend paying for XenCentral if you are not using it already, or you have no need of its other features.

Thank you so much! That seems to have solved the server issues -- and the log-in issues, from what I see. I'll ask the members if they're still being kicked and update within a day or two.

Closing this as fixed in the next release. In 4.1.1, if the wiki is configured to a different domain than the forum, cookies will be replicated for the opposite domain wherever feasible, in order to preserve the user's logged in state and preferences.

Please note that in XenForo 2, if this scenario is active, certain actions that were once instant refresh now have an intermediate redirect screen. This is because cookies cannot be reliably copied outside of the request where the original cookie was set (the redirect request vs a subsequent request), and because cookies for another domain can only be set by actually loading content from the other domain in the browser.
