I am running QGIS 2.18 on a mac and trying to use the Contours plugin. I've never had problems with it before but then I updated QGIS using Kyngchaos. Now Contours crashes QGIS when I choice "Filled Contours" or "Both". It works fine for generating just contour lines. When it crashes, it doesn't throw up an error window; the whole program just quits.
I tried stepping back to an older version of QGIS but that not only didn't solve the problem, it also created a host of other issues. I've also uninstalled and reinstalled the plugin.
How can I get Contours plugin fully functional again?
