Hi, I've been following your instructions and have deployed my app but am getting an internal server error when trying to access the website:

HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfil the request.

I logged all the steps that I took during deployment, and it all looks fine (except for the memcache installation, see below) so I'm not sure what's gone wrong here:

git remote add olp-heroku [email protected]:olp-main-website.git

git push olp-heroku master

Also, just looking at the db-related lines above, it looks like the db didn't migrate across.

I use memcachier now because you get more for free, it looks like memcache has been disabled.
https://addons.heroku.com/memcachier
Another thing I learned when I started playing with this is that I didn't have to create a DB one was created for me already. So I just used that one.
Also it would be nice if you could give us the exact error that you are getting. That is the error it is telling your browser, but if you could check your logs it would make it easier.
Thanks,
Chris

Thanks for that, Chris. These are the log entries when trying to access the app:

I see the same errors too, occasionally. And looking at @babaggeii's logs, it seems to be due to the favicon.ico and something to do with django-compressor. Here's my sentry log snippet from the same error:

OfflineGenerationError
You have offline compression enabled but key "xxxx" is missing from offline manifest. You may need to run "python manage.py compress".

...and the stacktrace:

  Stacktrace (most recent call last):

    response = callback(request, **param_dict)
  File "django/utils/decorators.py", line 91, in _wrapped_view
    response = view_func(request, *args, **kwargs)

  File "compressor/templatetags/compress.py", line 72, in render_offline
    'You may need to run "python manage.py compress".' % key)

Looking at the django-compressor docs, it seems the cache key is not being passed to the function. I'm still trying to figure out why this should happen with favicon.ico, but if anyone else has an answer, please help?

Thanks! :)
