I'm running my djnago application usind mod_wsg (I can't use built-in django server with some reasons)
When error occures and I see error 500, I'm looking for information in /var/log/apache2/errors.log , but there's no any useful information here.
If I have error with syntax or with database or in views - whatever! I'm getting error message about "UnicodeDecodeError". It looks like this:

I think that django tries to handle error exception and gets new error while this process. Something about encodings. But I don't know how to fix it.
How can I get information about my first error, not UnicodeDecodeError? How can I fix UnicodeDecodeError? (After fixing it I hope to see my first error description in logs).
Read the Django documentation where it talks about this:
https://docs.djangoproject.com/en/dev/howto/deployment/wsgi/modwsgi/#if-you-get-a-unicodeencodeerror
Also try setting DEBUG to True in Django settings module. It may allow the underlying error to be shown in browser. If this is a public facing site and you can't do that, then set ADMINS settings to email address as covered in Django documentation so details of errors are sent to you by email.
