Applying the patch
The application of this patch is relatively straightforward. I'd recommend doing this in staging/development before attempting on live (if you don't have a dev. site follow this guide to create one).
Change directory to your Magento document root and fetch
mda.phar(the Magento downloader tool), if using Enterprise, refer to the documentation here to provide your id/token.
cd /microcloud/data/domains/example/domains/example.com/http wget -O mda.phar --no-check-certificate https://raw.githubusercontent.com/sonassi/magento-download-archive/master/bin/mda.phar php mda.phar
Select either CE/EE patch as appropriate,
1: Ce-patch 3: Ee-patch
Select the auto detected version of Magento,
0: 220.127.116.11 (auto detected)
Select the SUPEE-10336 patch (or press
