I keep getting the same error:
The following layers were not correctly generated.
You can check the log messages to find more information about the execution of the algorithm
I saw two post about it on this forum but none of them helped me. I see that that it is related to the Grid but I don't know what it means (I used EPSG:4326 - WGS 84 and I put 0,0005 instead of 100 to convert in degrees).
EDIT: My version of QGIS is 2.18.1 Las Palmas (the last one). I followed this tutorial (https://www.youtube.com/watch?v=bLbY3iMBW-A) from 5:00 to 9:00 and I used 0,0005.
