I've tested it on clean install of yii2 adv and yii2 basic apps. Just Yii2+ yii2-user.
Debug bar works fine in every controller exept yii2-user controllers. Also, when I'm using code like Yii::$app->user->identity->profile-> (...) in other controller's views, debug bar also stops working.
I guess it has some problems with permissions (?) because runtime\debug is empty and I'm getting Unable to find debug data tagged with '58aab3e20d186' in console (404). When i'm using action line site/index new debug data file is made.
I'm using Windows 10 with Xampp, PHP 7.0.13
Clean Yii2 (stable) install (with clean cache).
I'd like to thanks author of this project. It is piece of great job.
