After upgrading my PHP to 5.4.3 (WAMP server 2.2), my web app made in CakePHP 1.3, is showing the following errors in my index:
Strict standards: Redefining already defined constructor for class Object in C:\...\cake\cake\libs\object.php on line 63
Strict standards: Non-static method Configure::getInstance() should not be called statically in C:\...\cake\cake\bootstrap.php on line 49
One of the changes in php 5.4 is that E_STRICT is now part of E_ALL
So, in your /cake/bootstrap.php you could remove the E_STRICT from your error reporting:
error_reporting(E_ALL ^ E_STRICT);
and be compatible again with before 5.4 versions.
