All geek questions in one place

Why the / admin application in debug mode false gives me a 500 server error

I changed the .py server settings from Debug = Trueto Debug = False.

I can get httpResponsesfrom my other application urls, but I can’t access the / admin url specifically , I get a server error (500)

I tried to change ALLOWED_HOSTS = ['my-app-name.herokuapp.com','*']how other topics of this problem say, but it did not help me in my case.

('*' was added only for this question and to show that I tried it, and this does not solve the problem)

This problem also occurred, but the solution was related to configuring nginx from a static location. Must be

location /static/ {
    root /var/www/fancy-project/;
}

instead

location /static/ {
    root /var/www/fancy-project/static/;
}

Maybe it will be useful for someone
