    When I open a MapThat Project I get an error message stating – sequence contains no elements – what is causing this?


    This issue can be resolved by ensuring that for the chosen project you have at least one layer associated to it. Using the MapThat Admin forms, simply tick to reveal a Layer in a specific Tree and also ensure that the Layer is visible by at least One Role.

    The Project will now open successfully.
