Strict Standards: Non-static method Configure::getInstance() should not be called

I Got this error as follows:

Strict Standards: Redefining already defined constructor for class Object in C:\Xampp\htdocs\webapp\cake\libs\object.php on line 54

Strict Standards: Non-static method Configure::getInstance() should not be called statically in C:\Xampp\htdocs\webapp\cake\bootstrap.php on line 38

I solved this problem by changing in /cake/bootstrap.php.

FIND:
error_reporting(E_ALL & ~E_DEPRECATED);

REPLACE:
error_reporting(E_ALL & ~E_STRICT & ~E_DEPRECATED);
