In my experience, it can be due to bad network. When rendering the pdf, QGIS
will download the needed layers again. When the connection to the servers of
online map-sources fail, result will be a blank layer or missing tiles.

Sorry, previously posted response under wrong subject:
Thank you. I have been doing some additional testing, it appears to

Hi Richard,
Do you have any basemaps from OpenLayers plugin in your composer? This is a
known issue with OpenLayers (http://hub.qgis.org/issues/11073). Try
removing the basemap layer and see if you are able to export. I have had
better luck with QuickMapServices plugin for basemap layers.
Hi Richard,
That's definitely not common QGIS behavior. Do you have access to a second
machine where you can reproduce the behavior? Can you share the problematic
project including data? Which data sources do you use?
Sorry, just questions and no answers at this point.
Best wishes,

I am relatively new to print composer, but have been able to develop some
nice annotated maps. I was able to successfully export to a png one time,
but since then, exports to png or pdf or svg all fail and empty the
canvas. If I exit out of qgis and re-start, I can find the previously
populated
