Unknown data property field_target_nodes.
I have tried for past few days and now even with latest release on Mar 28 Occurs just after your installer forces me to create an engineering group. Occurs when I install with sample content and without sample content.
When I just go to home screen it displays but ultimately get a server 500 error. There are no commons modules listed in modules list either.
I have tried this on MAMP local and on hosted server -haven't been able to get around it. Frustrating.
