Can´t create more than one content type group I am using Drupal commons for a community social network. I am trying to create a second group based on a content type named Leagues. In order to create that group I went to: /admin/structure/types/add, gave the group a name and selected the group check box (as the example given on this page: https://www.drupal.org/node/2014777).

But for some reason every time I try to create a new league and save it, I get this error:


  EntityMetadataWrapperException: Unknown data property field_og_subscribe_settings. in EntityStructureWrapper-&gt;getPropertyInfo() (line 335 of /home2/jane/public_html/devpage/profiles/commons/modules/contrib/entity/includes/entity.wrapper.inc).


It seems that the field field_og_subscribe_settings is attached to the content type group which I am not exactly sure what it means, but it seems I can´t create more than one group based on a content type.
It seems this solves your issue : EntityMetadataWrapperException

You probably need to add field_og_subscribe_settings field to your new content group type, and make it required.

You can take a look at 

/admin/structure/types/manage/group/fields/field_og_subscribe_settings

to see how it's been configured for the default group content type.
