Drupal website is broken on localhost I have moved a drupal website from live server to localhost.

But the problem I am facing is that everything is broken. no css, no images only text is visible on pages.

On my live website when I click on login button a popup for login appears. But on local host its not working. I have tried using different login URLs but non of them worked for me.

Here is a URL of one image : localhost/sites/default/files/Screen%20Shot%202015-02-24%20at%206.08.54%20PM_0.png

Similarly I have viewed source code of page and here are URLs of CSS and JavaScript files

localhost/sites/default/files/css/css_UCtZrZRD9npGm4D7o8VXPkl5qDJq-m8IlhuR9ccf_tY.css

localhost/sites/default/files/js/js_0gj6QcpfRH2jzTbCQqf7kEkm4MXY0UA_sRhwPc8jC1o.js

These images and files are not found in this location, is this a cache problem ? All these files and images are missing from this location : localhost/sites/default/files


  Note : Most of you are pointing me to following Path :


admin/config/media/file-system



  Here is what I have 


Public file system path : sites/default/files
Temporary directory : /mnt/tmp/test



  Now should I make both these paths empty ? or change the path ?
It seems that drupal can't process your files due to not writeable file system paths. 
Go to admin/config/media/file-system and specify public and temporary directories.
After that clear all cache here admin/config/development/performance.
