Fixed Login and logout errors

    On my test forum I am having problems logging in and logging out. It seems to be fairly consistent under IE8.

    Whenever I perform either action I get the following error:

    The resultant action is ok, I am either logged in or logged out but the error is displayed.

    I'll try and reproduce under FF.

    The last time I saw this, it was an Nginx misconfiguration.

    Hmm, let me check the logs.

    Have stripped back my config file to just the following:

    server {
            listen xx.xx.xx.61:80;
            server_name testforums.somedomain.com;
            root   /data/websites/testforums.somedomain.com;
            index index.php;
            location / {
                   try_files               $uri $uri/ /index.php?$uri&$args;
            location ~ ^(.+\.php)(.*)$ {
                    include /usr/local/nginx/conf/fastcgi_params;
                    fastcgi_index index.php;
                    if (-f $request_filename) {
                        fastcgi_pass phpfpm_backend;
    The problem still exists, looking in the logs I see the following:

    As you can see, the penultimate entry is giving a redirect which is then giving a 404 error and this then causes the error to be displayed.

    Doing the exact same thing in FF 3.6.15 gives the following log entries:

    Firefox is requesting different urls from IE8 to logout. Now if it was a configuration issue with nginx then surely I would see the same urls being asked for regardless, as that is a client side request.

    I think I fixed mine by putting "root" directives in my location blocks. I think

    Have tried that and it didn't work. My point still stands, from the server side logs IE8 is requesting a different URL from FF when logging out.

    I saw the same thing for a while when I was trying to setup my forum as a sub domain, but I thought it was an nginx configuration problem too, I saw exactly the same thing, that FF and IE8 were sending different redirects.

    This should fix it.

    In library/XenForo/Link.php, add the lines in red:
            if ($uri == '.')
                $uri = ''; // current directory
            if (substr($uri, 0, 1) == '/')

    Applied the fix and can confirm it now works as expected in IE 8. Many thanks.

    I guess I wasn't crazy. Thanks Mike.
