[ckan-dev] production deployment

Mon Jun 13 18:16:18 UTC 2011

Hi Pascal,

Sorry for slow reply! Questions:

* Can you run the site using paster serve? (and visit on port 5000 or
whichever port it starts on)
* Can you do python datalocale.cg33.fr.py without errors
* Are you running wsgi in daemon or embedded mode?
