On our test server we tried to add a second warehouse and a location to it.

After adding it, we tried to look at forecasted report for a item which was added to the warehouse, we then found out that when pressing it we can see a simple graph showing the amount on in the warehouse, but everything else is not showing, only an 404 error page

it dosnt matter if the warehouse is changed, and every other product now shows the same for every item.

Earlier this didnt work either before the new warehouse, but the problem was that "insecure content" was blocked, when putting it to allow, it worked.
Sadly this dosnt work for the new error.
