What is it with map providers! You may see something like this when you open a map view:
The changes Map Quest have put in place mean that they no longer support OpenLayers which is the mapping API that Smap uses in many places on the server. fieldTask is also affected.
More details on their announcement here: http://devblog.mapquest.com/2016/06/15/modernization-of-mapquest-results-in-changes-to-open-tile-access/
There is an updated version of the Smap Server to address this problem available on the downloads page. http://www.smap.com.au/downloads.shtml
A fix for fieldTask should be available soon.
