python-3.x - Method Not Allowed (POST) in Django 3.1

Question

I am new to Django. Practicing in a small project in Dango 3.1 I get the error "Method Not Allowed (POST)". The error appears when a user presses the Guarder (Save) button.

Method Not Allowed: /pizarra/comunicado/
[30/Jul/2021 09:10:03] "POST /pizarra/comunicado/ HTTP/1.1" 405 0

Everything was working before and I can't understand what I'm doing wrong. Please if someone can help me. Thanks in advance.
