I am using ArcMap 10.0. I am in Layout View using both 11x17 Paper and 11x17 Map Page size. My map is bringing in an aerial image from this WMS: http://services.nconemap.com/arcgis/services/Imagery/Orthoimagery_2013/ImageServer/WMSServer
If I set the paper and map page size to landscape, I can export to PDF just fine. If I set the paper and map page size to portrait, the aerial does not display on the exported PDF - only the vector layers do.
What am I missing?
