 * Getting php strict error. PHP Strict Standards: Declaration of DropDown_Nav_Menu::
   start_lvl() should be compatible with Walker_Nav_Menu::start_lvl(&$output, $depth
   = 0, $args = Array) in /home/villageo/public_html/wdpr/wp-content/themes/smartbusiness/
   functions/dropdown-menus.php on line 113
 * Anyone know what code needs to be changed (note code was put exactly into a theme).
 * Found this
    [https://wordpress.stackexchange.com/questions/111557/strict-standards-error-bootstrap-navwalker](https://wordpress.stackexchange.com/questions/111557/strict-standards-error-bootstrap-navwalker)
