Just getting started with GeoServer and already running into problems. When I click on Layer Preview and view any of the preloaded data in OpenLayers (or any other format) it is just blank and has the missing image icon where the data should be. One interesting thing is that I could click randomly in the blank map and see attributes of selected polygons appear so I think the data is partially loaded. Example screenshot.
I've installed it on multiple machines and I am getting the same exact problem. I have connected my own data through PostGIS but I got the same result. That is why I am assuming it is user error. Anyone have any ideas?
