Backlog blank - all items are not visible

[Tony Scarborough]

Changed over the weekend - now we can't see anything in our backlog.

Kindly go to the board configuration and find the board filter on the General tab. Try to execute the filter in the Issue Navigator and have a look, if you can see issues in the result part of the issue navigator. If you can not see any issue, then check the browse issues permission on the projects, which are queried by the filter.
