Hi Manuel,

What versions of Wagtail, Django and django-compressor are you running?

Cheers,

I want to make my wagtail site production ready, since I turned my DEBUG setiing to False I cant access Wagtail admin anymore. Django-admin and the rest of the Site is working well except of the Wagtail userbar which also raises a 500 error on every page (http://manuelstrasser.com/admin/userbar/3/ 500 (Internal Server Error)). I guess that's an issue with compressing. After I run collectstatic, I tried to python manage.py compress which gives me the following errors:

In my settings I've 

COMPRESS_ENABLED = True

COMPRESS_OFFLINE = True

ALLOWED_HOSTS = ['*',]

Any Ideas how I could get Wagtail admin work again?

Hey Matt,

Thanks for quick respond. I used wagtail==1.3.1 and django-compressor==2.0. Anyway I guess my suspicion was right that it has to do with compressing, I read about the new Wagtail release and noticed that django-compressor isn't required any longer, so i updated wagtail to 1.4 and now Wagtail admin working fine, and I'm very lucky but still it would be interesting to me how I could have solved it with wagtail 1.3 and django compressor since it's still the recommended way. 

Cheers
