Rocket Chat not showing OpLog deactivated


I am trying to prepare rocket chat for the upgrade to 1.x. If followed this guide to enable replica sets. The changes run without error but when I check RocketChat it still says OpLog deactivated. I know this is little information but where would I start to look for more information what is going wrong?
