Drupal organic groups extras add content links

If you’re using Drupal 7 and Organic Groups (2.x) you probably have the OG extras module enabled.

The documentation to enable the “create content” links for your organic group nodes is sparse. Therefore a short howto:

1. Enable all needed modules
2. Enable the module entityreference prepopulate!
3. Go to “Structure” -> “Content types” and select your group content type, not your group type.
4. Click on “manage fields” and edit the field “og_group_ref”.
5. Enable the checkbox labeled “Enable Entity reference prepopulate”.
6. Enable the block named “Node content links”.

Now you should be done. Steps 4-5 are needed for every group content type in case you have multiple content types that can be posted to groups.
