Hi, I upgraded to the latest dev (2012-Aug-28) to fix the wms url length problem (http://drupal.org/node/1512486). It seams that since that, the Base URL field is always empty. It remains empty after saving a new layer and edit it. But it is also empty if you edit an existing default layer like "MapQuest Open Aerial". Fortunately the existing layers still work.
