Please create alle your contenttypes on this SiteCollection. If you are ready you have to publish this contenttype.
In the Manage ContentType form you have the button “Manage Publishing of this ContentType”.
Please click on Publish and OK to publish this contenttype to all SiteCollections:
This operation takes a while. A timerjob which runs every hour needs to start in SharePoint in order to publish your contenttypes. So be patient and wait up to 1 hour to get your contenttype published.
