问题 When I set the option in Yii to remove index.php from the URL I get a 404 error and this error in the error logs File does not exist: /var/live/var . In my browser I get this error The requested URL /var/decat/frontend/web/index.php was not found on this server. but the file is exactly in that location.

问题 I'm trying to display in a view an image loaded in a controller (the image folder is not available directly from the view). I can correctly load the image in the controller but I did not find the correct way in order to provide the view with it.
