Error when hosting


I created a website based on soratemplates. It worked fine in local. i uploaded it on a test domain with and again it worked fine. Then I bought another domain on, uploaded the exact same files but now the css is not working. I get only text, no layout or pictures.
Where could I look to find the problem ?
Thanks in advance.

Check the developer console (F12 in Chrome) and see what errors pop up. This is likely an error with paths, routes, or redirection in either the theme or the domain-setup (including .htaccess), but always visible from any console-logs as missing resources are public.

Indeed, it helped me find the problem. It was a permission error. After changing it to 755, it works fine from now on.
Thanks a lot for your help
