Technical problems with viewing ASAP 8 roadmap

Hi,

today I've tried to view the different ASAP 8 roadmaps at the Service Marketplace, however, I am facing some technical challenges here ..

After having selected a roadmap (e.g. Agile ASAP 8) I only get the skeleton screen as shown above, with no phases, deliverables, etc.

Any suggestion what causes this malfunction?

Thank you and Regards,

Christian
