Search for OHL licenced projects fails now
At https://www.ohwr.org/project/cernohl/wikis/CernOhlProjects and also at http://en.wikipedia.org/wikis/CERN_Open_Hardware_License is a link to
"Most projects in the Open Hardware Repository OHR": https://www.ohwr.org/projects?custom_fields%5B2%5D=CERN+OHL
This link originally would return all OHR projects using the CERN OHL licence. But it now returns an empty list.
It must have worked before. Can you have a look at it?
