I got GeoServer up and running today and created a store that is linked to my postgis database, with a layer corresponding to one of the tables in the database. I then previewed the layer using the GeoServer Layer Previewer and it all worked nicely.
I began messing around with GeoServer, trying to get this layer plotted on my own OpenLayers map, and now none of the layers work in the Layer Previewer. When I click "go", a new tab opens with a blank box where the map should be, and the tab indicates that it is loading. However, it does not ever appear to load correctly.
Does anybody have any idea what I might have done to mess this up?
