I am using Organic Groups on a Drupal 7 website. I created a Group Content type and a few user roles. The user roles are defined in the Drupal roles (and not OG roles).
I want to make sure that a user role can create and edit the Group Content, but not delete it. I enabled all necessary permissions in the Drupal permissions, but I get an internal server error when trying to create the content.
However, when I set the Drupal permission "Administer Organic Groups permissions" the user role can create content.
One unwanted side-effect is that the user role can then also delete content. Does anyone have an idea how to solve this?
