Pantheon Site to Local Environment I have recently inherited a Drupal 7 site running on Pantheon.io
I have set up a local Drupal 7 server for a dev/test environment that is working flawlessly as a fresh install.
However, once I put the code, files, and database backups in place, my content appears, but there is no theme or CSS present, none of my links work, etc. 

I have a feeling there is a simple fix for this, but I have exhausted my limited knowledge of this platform.
Clone the code
Import database
Configure your settings.php file
Get public files; copy them to sites/default/files
Compile CSS and JavaScript in the theme, if it is required
Clear the cache  


Those step should works.

If Backup and Migrate module installed in Pantheon.io
you can get the database and public files from https://pantheon.io/admin/config/system/backup_migrate.
