Drupal works fine when a user is logged in. After logging out, everything is white-screened. In php's error_log, this appears:

PHP Fatal error: Call to undefined function drupal_get_path() in /Users/Steven/src/drupal/sites/all/modules/subscriptions_og/subscriptions_og.module on line 21

On my installation, anonymous users have "access content" permission unchecked.
Manually disabling the subscriptions_og module in the system database table allowed me to get back in.

This error appears with the dev version committed June 25, 2008.

Title: Anonymous visitors see white-screen with Drupal » Anonymous visitors see white-screen with page caching on

Under admin/performance I disabled page caching, and re-enabled subscripitons_og. Now page viewing as anonymous seems to work.

A lot of contrib modules seem to have an issue with caching. For example:
http://www.google.com/search?client=opera&rls=en&q=call+to+undefined+fun...
http://drupal.org/node/54609

I'd still say this is a critical bug since normal users who don't know how to change the database will find it impossible to log back in.
