CSS not applied on install, but loaded properly I have installed Drupal 8, but the default CSS is not applied (see http://ec2-54-187-215-79.us-west-2.compute.amazonaws.com/user/1 for example). 



Chrome's 'inspect' functionality reveals that the CSS is loaded properly from http://ec2-54-187-215-79.us-west-2.compute.amazonaws.com/sites/default/files/css/css_4w6DyMZOD_Fu1oxqpACBFcOPDgVYtgOuayu9S6-8btc.css?0

What is causing this issue? How can I solve it?
When you installed it, for Installation Profile, did you select Standard? or did you select Minimal? 



It seems like you selected Minimal, which I highly do not recommend, Standard is the way to go. Delete all the tables in your DataBase and go to http://ec2-54-187-215-79.us-west-2.compute.amazonaws.com/install.php and install again.
