"No module named slimmer.middleware"

I'm trying to setup blog engine django-mingus, but meet this obstacle:

When I start Django development server it works well, but through Apache+mod_wsgi it appears this issue. Wha开发者_JS百科t could be the reason of this problem?

Read:

http://blog.dscpl.com.au/2010/03/improved-wsgi-script-for-use-with.html

Try the alternate WSGI script file described at the end.

This will resolve some sys.path issues if you hadn't done anything to address them yourself.

If still doesn't work, may be a permissions issue given that Apache normally runs as different user and so may not be able to read code if that code was only readable to you. See:
