Actually i begin the upgrade for Yii framework and have the next error:
class_exists(): Passing null to parameter #1 ($class) of type string is deprecated
in C:\wamp\www...\vendor\yiisoft\yii2-debug\src\panels\UserPanel.php
I upgrade the yii version from 2.0.6 to 2.0.45 and the php version from 5.5.12 to 8.1.13
