Permissions Sitecake in domain

I have 1 project executing in Sitecake.

Project is running in local perfectly. But in customer domain not run. I got

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator at [email protected] to inform them of the time this error occurred, and the actions you performed just before this error.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Sitecake need specific permissions?

In order to run correctly, Sitecake has to have permissions to write to the where it is installed (the site root folder). It also needs to be able to write (modify/delete) html files in the site root folder. By default Sitecake tries to write to the site root folder as the PHP user/process. If the PHP process does not have proper permissions, it is possible to use FTP protocol for modifying files in the site root folder. For this, please consult the config.php file (sitecake//server/config.php).
