I’ve just upgraded my servers to PHP 5.4 and got this error when loading a project.
Declaration of MyModelName::beforeSave() should be compatible with Model::beforeSave( $options = array() )
There seems to be a problem when using PHP 5.4 and CakePHP 2.1 which results in this error. Since PHP 5.4 E_ALL and E_STRICT are now combined and with a default CakePHP installation error reporting is set to E_ALL & ~E_DEPRECATED!
Luckily it is really easy to fix!
