It's incredibly wasteful to read through this old documentation when none of it applies whatsoever to your new UI. All the screenshots are wrong. There aren't the same options. It's confusing and lazy on your part.
I understand you have a lot of users and you don't want people opening support tickets for every single question, but in order to have a self-sustaining forum you need to ensure you have accurate documentation available.
You seriously need to implement documentation into your project management and ensure any new release coincides with the release of new documentation.
