I have a client's site that is currently using Mag 18.104.22.168 and need to apply the latest patches. I've applied both 10266 and 10336 (in that order) - all good. However on the description for 10226, it states the following:
SUPEE-10266 for Magento Commerce (Enterprise Edition) includes a fix for a functional issues MPERF-9685, related to checkout with a zero order amount. This fix is not included in release 22.214.171.124. However, in some cases, SUPEE-10266 can cause issues in the checkout process. Specifically, if a customer enables the Add gift options checkbox during checkout, the checkout process will not progress beyond the payments step. Magento released a fix for this issue as a new patch SUPEE-10348, that needs to be installed on top of SUPEE-10266.
I can't find the download for 10348 anywhere, and I do not have Magento support, so how do I install this patch?
