Metatag error in Drupal 7 prontpage

After implementing metatags in on of my Drupal sites, I realized Metatags weren't rendering in the front page, but were in every other.

After searching the net I found this post:

https://www.drupal.org/node/1386320

The problem seems to occur only on sites that don't render any actual content on a page (blocs don't count).

The solution I aplied was simply to add

<?php  
render($page['content']['metatags']); 
?>

To The page.tpl.php of the current theme.

Hope it helps!
