Strict Standards warnings in 3.7.1

[boboz]

Hi,

I get two Strict Standards warnings in WordPress 3.7.1
Anyone knows how to fix this?

Strict Standards: Declaration of The_Bootstrap_Nav_Walker::start_lvl() should be compatible with Walker::start_lvl(&$output, $depth = 0, $args = Array) in C:\UniServer\www\wp37\wp-content\themes\the-bootstrap\inc\nav-menu-walker.php on line 104

Strict Standards: Declaration of The_Bootstrap_Nav_Walker::start_el() should be compatible with Walker::start_el(&$output, $object, $depth = 0, $args = Array, $current_object_id = 0) in C:\UniServer\www\wp37\wp-content\themes\the-bootstrap\inc\nav-menu-walker.php on line 104
