Uninstalling django-dagging-autocomplete

I've used setuptools to install django-tagging-autocpmlete. I then added all ne开发者_开发问答cessary settings to the settings file (INSTALLED_APPS, etc) and it worked fine.

When I wanted to remove the app, I took it off my INSTALLED_APPS list. The problem is that now I get

TemplateSyntaxError at /admin/ "Caught ValueError while rendering: Empty module name"

when trying to access my admin panel. What can cause this problem?

Thanks,

Meir
