How to resolve this GAE status 500 error

Hi I'm looking for how to resolve an error on the production server where AFAIK the instruction looks correct:

from google.appengine.ext.webapp import template

When at the log it says

<type 'exceptions.ImportError'>: cannot import name template

On the local开发者_开发百科 dev server it works normally. I suspect it's a problem with starting an instance on the production server. The appengine console says there totally is 1 instance. Could you please inform how I could proceed? Thank you

I had a similar problem this morning.

If you just updated to the new version (1.4) that was released today, you might need to update you paths. (I use mac and hade do lunch the Google App Engine Launcher to set the new paths.)
