That is quite interesting. The two options are
1 Users must be registered and log in to view the journal site.
2 Users must be registered and log in to view open access content.
With 1 or with both ticked the searches are not possible and I cannot even access "About the journal"
With only 2 ticked I would have thought the papers would not be able to be viewed but they can be, and everything else on the site works as if I am logged in.
