I apologize for the bad English. I bought a new computer, moved my files, installed all my libraries, and wanted to get my work back on its feet. But I encountered an unexpected error, the problem is exactly as follows ![hata1](https://us1.discourse-cdn.com/flex026/uploads/djangoproject/original/3X/8/5/85fdcf6ad43fe9ed9af4a775842a4d8d63e76edd.png) ![hata2](https://us1.discourse-cdn.com/flex026/uploads/djangoproject/original/3X/0/b/0bffb9cfed063dfe3cab3e6c18c268b45c38f8c8.png) The error I received is like this. I did research on how to solve the problem, but I could not find a solution. I am grateful in advance to those who will solve this problem of mine. Good work. ---

Your code appears to have been written for an earlier version of Django and Python. In the [Django 5.0 Release Notes](https://docs.djangoproject.com/en/5.0/releases/5.0/), it states: > - `django.contrib.sessions.serializers.PickleSerializer` is removed. You need to update your code to use a different serializer.
