'maxExtent has no properties' is usually an error masking the fact that
you don't have a base layer set on your map. Are you using all overlays, and 
no base layer? (If you look at the layerswitcher control, added via
map.addControl(new OpenLayers.Control.LayerSwitcher()), base layers are
radio buttons, and overlays are checkboxes.)

Again, without an example HTML page to look at, or a publicly visible
link, debugging this situation further is difficult. Without either of
those, I can't offer any advice on why this might be happening.
