Why isn't my custom region showing up? I'm trying to create a new region called 'usermenu' for my theme in Zen. I've therefore added

region[usermenu] = User menu


to the mytheme.info file, added

&lt;?php if ($logged_in): ?&gt;
  &lt;div id="usermenu"&gt;
    &lt;div class="menu"&gt;
      &lt;?php print render($page['usermenu']); ?&gt;
    &lt;/div&gt;
  &lt;/div&gt;
&lt;?php endif; ?&gt;


to the mytheme.tpl.php file and added

#usermenu {
  background-color: #fff;
  height: 35px;
}


to one of my CSS files. After clearing caches multiple times, the new region is displayed correctly and I can detect it with Firebug, but it doesn't show up in the block section.

What's going wrong and how can I solve this?
I found it! It was just a stupid typo in the .info file. I should have inserted regions[usermenu] = User menu...
