Drupal, Search Api Ajax and Media Center theme, strange facet behavior, how to fix?

Question

Drupal

In Garland's (standard) theme, the module works fine with these settings

<?php
function ajaxified_catalog_search_api_ajax_modules_alter(&$modules) {
$modules[] = 'block';
}

/**
* Implements hook_search_api_ajax_settings().
*/
function ajaxified_catalog_search_api_ajax_settings() {
$settings = array(

// required: CSS ID for the main content (search results html)
'content' => '.region.region-content',

// required: array of regions with search -related blocks => CSS ID's
'regions' => array(
'sidebar_first' => '#sidebar-first',
'sidebar_second' => '


// optional: if you want to show a spinner image on AJAX
/*'spinner' => drupal_get_path('module', 'search_api_ajax').'/spinner.gif'*/

);

return $settings;
}?>
In the Media Center theme, there is an error "jquery.js:5986 Uncaught TypeError: Cannot read property 'createDocumentFragment' of undefined" which I have been struggling with for the second day.

The HTML markup is the same. Anyone can help?

Answer 1

By mistake and a small amount of sleep, I registered two regions settings at once in two modules and two sidebars came to the array.

Answer 2

Hard to tell without theme code, see if Media Center requires a newer version of jQuery.
