On our project, we have a preview button for content. When we set the group(s) and "group" visibility option, pressed the preview button, and went back to editing I received the error "group visibility is not allowed". It is because of the disabled group option.
- Enable preview for nodes
- On adding node set group with "group" visibility option
- Press the Preview button
- Go back to editing process
In the "social_group_field_widget_single_element_form_alter" instead of getting "groups" from form values use the user input, as form values do not always exist after the preview.

Code (back-end)
We ran into the similar problem, but under different conditions:
The content-type has an additional upload field.
Whenever we set the (closed) group first and upload a document afterwards, the validation introduced in SocialNodeForm 80a5c4c triggers this error when trying to save (create) the node.
This patch fixes the issue for us.
