I am using QGIS (version 2.10.1-Pisa) on a Mac (Yosemite). I am trying to export a map in the print composer as jpg or pdf and whenever I do try, the page in the print composer goes blank. when trying to save as jpg, a file is saved but the image is black. it also saves a pdf but the file is empty. I am basically trying to print some simple vector layers on top of a google hybrid background.
