Q:

CKAN error after enabling harvester module - 'module' object has no attribute 'ITranslation'

After enabling the harvester module for CKAN, I'm getting the following error in ckan_default.error.log (and the web application returns status 500 until I disable the harvest and ckan_harvester plugins from config file):
mod_wsgi (pid=1605): Target WSGI script '/etc/ckan/default/apache.wsgi' cannot be loaded as Python module.
mod_wsgi (pid=1605): Exception occurred processing WSGI script '/etc/ckan/default/apache.wsgi'.

I found some similar errors but not for CKAN and 'ITranslation', any help appreciated.
Thanks

A:

Fixed it! Just upgraded current 2.5.0a installation to latest DEV version (2.6.0a) and it worked without problems...
Thanks!
