The USGS National Map basemap is throwing black box errors this morning. The Flex Viewers in production are throwing this error since this map is part of the basemaps normally available.
Thanks,

Solved! Go to Solution.
For a permanent work around to this problem, see this post of Bjorn Svensson on July 19, 2017 at 10:28am. I prefer option 2 myself. Hope this helps.
