Errors after updating to WordPress 3.6 (with solution)

If you’re getting PHP ‘Strict’ errors after updating to WordPress 3.6, here’s a solution that worked for me:

In the ‘include’ folder inside the main plugin folder, open up ‘terms_walker.php’. Replace the TO_Terms_Walker class defined there with the following:

class TO_Terms_Walker extends Walker
        {

            var $db_fields = array ('parent' => 'parent', 'id' => 'term_id');

            function start_lvl(&$output, $depth = 0, $args = array())
                {
                    extract($args, EXTR_SKIP);

                    $indent = str_repeat("\t", $depth);
                    $output .= "\n$indent<ul class='children sortable'>\n";
                }

            function end_lvl(&$output, $depth = 0, $args = array())
                {
                    extract($args, EXTR_SKIP);

                    $indent = str_repeat("\t", $depth);
                    $output .= "$indent</ul>\n";
                }

            function start_el(&$output, $object, $depth = 0, $args = array(), $current_object_id = 0)
                {
                    if ( $depth )
                        $indent = str_repeat("\t", $depth);
                    else
                        $indent = '';

                    //extract($args, EXTR_SKIP);
                    $taxonomy = get_taxonomy($object->term_taxonomy_id);
                    $output .= $indent . '<li class="term_type_li" id="item_'.$object->term_id.'"><div class="item"><span>'.apply_filters( 'the_title', $object->name, $object->term_id ).' </span></div>';
                }

            function end_el(&$output, $object, $depth = 0, $args = array())
                {
                    $output .= "</li>\n";
                }

        }

This is just an update to the arguments in the function definitions so they match the Walker class that this plugin’s class inherits.
