Group URLs not rewriting properly

First question: have you enabled Clean URLs?
That's a requirement I neglected to add to the Readme.txt

2nd Question: are you setting this up on Shared Hosting? or your own server (virtual or otherwise)...

If Drupal is generating subdomain links on your site correctly, your pathauto and subdomain settings are good to go.

If browsing to a subdomain link takes you to the frontpage, however, it means Apache is not rewriting your subdomain URLs correctly.

If Clean URLs is enabled and working, the problem is either your .htaccess file:

It should read at the bottom as follows:

  # REQUIRED BY SUBDOMAIN.MODULE
  # Moves subdomain to URI path
  # e.g: mysubdomain.example.com 
  # becomes example.com/index.php?_mysubdomain/
  # NOTE: does not rewrite subdomain if it is "www". 
  # If you want it to rewrite www, disable the 2nd line
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{HTTP_HOST} !^www\.([^.]+)\.([^.]+)$
  RewriteCond %{HTTP_HOST} ^([^.]+)\.([^.]+)\.([^.]+)$
  RewriteRule ^(.*)$ index.php?q=~%1/$1 [L]

  # Rewrite current-style URLs of the form 'index.php?q=x'.
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]
</IfModule>

or your Apache configuration:

In your apache config, you'd need to have an "AllowOverride All" in the section of the definition for your website.

If you've got everything setup as described above and it's still not working, can you do a quick test for me?

1) backup your index.php file (e.g. cp index.php index.php.save)
2) replace the contents of index.php with the following:

<p>HTTP_HOST: 
<?php print $_SERVER['HTTP_HOST'] ?>
<p>QUERY_STRING:
<?php print $_SERVER['QUERY_STRING'] ?>
<p>REQUEST_URI: 
<?php print $_SERVER['REQUEST_URI'] ?>

3) save and then surf to a subdomain URL (e.g. getupstandup.windycitizen.com)

The output (for getupstandup.windycitizen.com) should read:

HTTP_HOST: getupstandup.windycitizen.com

QUERY_STRING: q=~getupstandup/

REQUEST_URI: /

If the above doesn't work (i.e. the output isn't as shown above), the easiest thing would be for me to walk through the problem with you via a skype / remote-access / remote-control session online. If you'd like to do that, just shoot me an e-mail and we can figure out the details.

After working with bflora, we discovered the issue was the compound result of an incorrectly configured apache configuration file and a conflict with the globalredirect module.
