[OpenLayers-Dev] Why I cant open WMS layer?

Fri Oct 29 02:44:17 EDT 2010

I think it's not you but the server layer who's causing the error (assuming
that you refer to 'jpl_wms' layer). If you replace 'landsat7' layer with
'overview' layer you'll notice that there's no error, just a blank image,
which means that even the server is OK but not is the layer. You would try
with another WMS server
