I have a clean install of **Magento 2.1.3** with sample data. No themes or plugins have been added.

**When I create a new role, the role resource tree does not display**, and there is no other error or warning on the page.

There are some posts related to earlier Magento releases that speak about the `acl.xml` file requiring change - and yet others claiming to have fixed the issue by changing folder permissions **(no folders were listed, nor were we shown which permissions needed to be changed).**

If I have to go through the entire Magento documentation I will, but the point of coming to any forum is to share information and hopefully save time.

Should I come across the solution, I will come back and post the answer. If anyone has already tackled this, a detailed response would be appreciated.

Disclaimer: I am very new to **Magento 2.1x** - the most recent Magento experience I had was **CE 1.7**.

**Thank you in advance to all!**
