SetEnv APPLICATION_ENV development

I've been unable to retrieve error messages in Omeka 2.0 using the instructions here: http://omeka.org/codex/Retrieving_error_messages#Omeka_2.0

I've uncommented the following in .htaccess:
SetEnv APPLICATION_ENV development

It simply doesn't do anything on either existing or fresh installs. I'm wondering if it is host-related (I'm on Webfaction). Any ideas?

I think it is a host setup issue. Webfaction seems to use suExec to host PHP, and it scrubs out most environment variables.

You can manually define the constant at the top bootstrap.php:

define('APPLICATION_ENV', 'development');

Perfect, thanks John.
