heroku - django debug false and internal server error -

im writing project using django.

while in development stage used debug=true, want upload heroku production.

i set debug=false , kept getting internal server error, further investigated , found need set allowed_hosts = ['localhost', '127.0.0.1'], did..

i ran localhost still kept getting internal server error.

what doing wrong? cause can't figure out?

also, should put in allowed host heroku site?

thanks

try this

python manege.py collecstatic 

remember static files directory when debug = true no same when debug false

heroku uses whitenoise static files.
