[Geomoose-users] GM 3.2.1 disappearing raster

[James Klassen]

That certainly seems odd.

Did the MapServer version change?

Does the TIFF have overviews?

If I remember correctly, GeoMoose 2.9 and 3.x are both using WMS to access
MapServer behind the scenes.  The actual request is likely slightly
different due to OpenLayers 2 vs OpenLayers 3+ being used for the map
widget.

If you look in the browser developer tools you could see if/how the
requests differ.
