Grey lines on an exported SVG
Hi guys, I'm new to Illustrator this week so I'm slowly learning things but I have come across a problem.
My illustrator (.ai) file is perfectly fine and indeed a very good vector when zoomed in on. However, when I have exported the file as an .svg there are strange grey lines present which makes the image look ugly. See below.

You can notice the grey-ish lines mostly on the green and orange segments with the surrounding black perimeter.
Is there any possible way to fix this? Adobe Illustrator CC 2017.
Thanks!
