Trying to install Laravel app on hosting

Hi I hope someone can help me I have an application that uses the Laravel framework I have uploaded the main app to a folder on my host named script I have set my www.domain.com folder to use public as its root

so I have a folder structure like this:

/ script public

I have set the file paths in my index,php file to:

require DIR.'/../script/bootstrap/autoload.php'; $app = require_once DIR.'/../script/bootstrap/app.php';

When I run the script installer it asks me to set the script/public folder to be writable so it looks like the installer is not seeing the correct path.

In my installerRepository.php I have these lines

//this function creates all required directories for theme in public folder
public function createDir($theme)
{
    if(!Storage::has('/public/themes/'. $theme))
        Storage::makeDirectory('/public/themes/'. $theme);
}

//copy assets contents to themes/{theme} folder
public function copyAssets($theme)
{
    $src  = base_path()."/resources/views/themes/{$theme}/assets";
    $dest = public_path()."/themes/{$theme}";

Which I presume will copy the contents for the themes to the public folder so the site will display correctly

is there a way to set the new path for the installer to use

thanks

Mike
