ReOrder Post Within Categories - fatal error: call to a member function get_queried_object() on a non obect

I am using a wordpress plugin called 'ReOrder Post Within Categories'. Using this plugin we can sort all the posts inside each categories. After installed this, I received a php error like this

Fatal error: Call to a member function get_queried_object() on a non-object in /home/content/04/10980904/html/wp-content/plugins/reorder-post-within-categories/reorder-posts-within-categories.php on line 96

The code in line number 96 is

$queriedObj = $wp_query->get_queried_object();

Note: $wp_query is already declared as global variable,

global $wpdb,$wp_query;

Can anyone help me to solve this issue.
