When I make two dashboards, create a public link for each, and then make a link from the first to the second through a text label, then the error “Unknown dashboard / Info: Nothing to show on this dashboard!” appears. If I then refresh the page, it shows the second dashboard. When I click the back button to return to the first dashboard, again the error comes, and refresh solves it.
You can see it here. Click on “History graphs” to see the problem.
Is that a bug or am I doing something bad?
