Move footer structure to html.tpl.php I've attempted to move the footer structure of a theme from page.tpl to html.tpl so the footer elements can occur outside of internal width specific layout.

In doing so I receive an error:  


  Fatal error: Only variables can be passed by reference in....


One of the many lines in question is:

&lt;?php print render($page['footer_first']); ?&gt;


Can someone explain what exactly the issue is here and how I can best solve it ? Muchly appreciated!
I am not too sure what this error would be caused by but I would recommend instead of putting the footer into the html.tpl.php put a wrapper div around the other elements within the page.tpl.php excluding the footer and styling that wrapper with a specific width.

eg.

    &lt;div class="wrapper" width="960"&gt;
      //all content in here
    &lt;/div&gt;
    &lt;div class="footer"&gt;
      //footer here
    &lt;/div&gt;
