[ckan-dev] DataStorer extension location question

Wed Jun 13 23:02:21 UTC 2012

Hi Adrià,

Thanks for the suggestions -- every command ran successfully until I
restarted Apache.  I'm still getting a 500 error when I try to access
CKAN, and the "PluginNotFoundException: datastorer" in the error logs.

Would the rest of the Traceback help you troubleshoot?  Any other suggestions?

Thanks again,
Jim

PluginNotFoundException: datastorer
