Anybody?

The issue is that one of your modules doesn't have a title defined in the acl.xml file. The easiest way to fix this is to update in src/vendor/magento/module-integration/Helper/Data.php to have:
$item['data'] = isset($resource['title']) ? $resource['title'] : '';

This will enable the UI to load but for one or many of the modules will have a blank space next to the folder. You then need to let the module developer know to fix the issue, but as a short term fix just add a title attribute to the acl.xml for the module yourself.

Still have this error on 2.1.2, how to fix? @sheldmandu
