The Atahualpa theme was updated to 3.7.11. Now Dynamic Content Gallery disappeared from home page. I don't see DCG's php code in the index template. Placing code in index.php doesn't make gallery show on homepage. I have tried both is_front and is_home. What am I doing wrong?

PHP Code:

<?php if( is_front() ) 
  { ?>
    <?php dynamic_content_gallery();
  }
?>

Where should the code be placed? Nothing happens when right after get_header().

what is the url?
what are you displaying as your landing page (dashboard->settings->reading->front page displays)
if you (or someone else) had add code to the index, it would have been replaced when the new index.php was copied into the theme folder.
