Need to add this code in functions.php on child theme
add_action(‘wp_head’, ‘my_post_nav’);
function my_post_nav(){
if ( !function_exists(‘wp_pagenavi’) )
return;
remove_action( ‘__after_loop’ , array( TC_post_navigation::$instance , ‘tc_post_nav’ ), 20 );
add_action( ‘__after_loop’, ‘wp_pagenavi’, 20 );
}
