prestashop 1.6, css files isn't loaded in back-office

Question

After charged project into server, css files isn't loaded in back-office,despite I emptied the cache, but in front-office all things is nice.

css files i need to load is admin-theme.css and overrides.css. they exist in
\admin-xxx\themes\default\css folder .

Answer 1

I found the solution. PrestaShop was using an old admin directory, because I have done migration from 1.5 to 1.6. I've changed the name of this directory and now everything is ok.
