Here is an update. I did some tests and I even put my k11e files back to my testing site. EMS intl quote still doesn't showup. Not sure what happens here. My k11e files are working fine in my live site (showing the proper EMS intl quote)

Hi @dbltoe, thanks for your suggestions. I tested the quote by a 0.64lb package, so it should not trigger the max limit. I also checked the page Shipping/Packaging between my test site and live site. They are the same.
