Question

I'm trying to serve a Django app (helios) with Apache2, but I'm always receiving this " There was an error while handling your request. when trying to access the server. The server have the following naming debian.serverdomain and I tried to access using http://debian.serverdomain , http://debian.serverdomain:80 and http://<hostname ip>:80 , but didn't work.

The apache configuration didn't show errors and the wsgi appears on the apache status.

The apache conf: helios.conf

[Solution] The problem was the database privileges, where I didn't created the apache user www-data . It seems to be an old issue, but the commands are there:

sudo -u postgres createuser www-data
sudo -u postgres psql -c 'alter user "www-data" with createdb;' postgres
sudo -u postgres psql helios -c 'GRANT ALL PRIVILEGES ON ALL TABLES in SCHEMA public to "www-data";' postgres
sudo -u postgres psql helios -c 'GRANT ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA public to "www-data";' postgres
sudo -u postgres psql helios -c 'GRANT ALL PRIVILEGES ON ALL FUNCTIONS  IN SCHEMA public to "www-data";' postgres
