I installed Roumen\Sitemap via composer on my development machine running an existing Laravel 5.3 project and setup the service provider & middleware route. It all worked great on my development environment.
I uploaded the following files & folders to a webserver via FTP.
/Http/Kernel.php (added ''sitemap' => '\App\Http\Middleware\Sitemap',' to the protected $middleware variable)
/config/sitemap.php
/config/app.php // (added Roumen\Sitemap\SitemapServiceProvider::class)
/public // (for some vendor views and assets)
/Http/routes.php // (just for retrieving the sitemap)
/Http/Middleware/Sitemap.php
Just to be sure, I ran sudo chmod -R 777 vendor and sudo chmod -R 777 storage
But I get the error:
production.ERROR: exception 'ErrorException' with message 'file_put_contents(myproject/bootstrap/cache/services.php): failed to open stream: Permission denied' in /myproject/vendor/laravel/framework/src/Illuminate/Filesystem/Filesystem.php:111

Did I forget something?
'ErrorException' with message 'file_put_contents(myproject/bootstrap/cache/services.php):
failed to open stream: Permission denied'
It's pretty obvious that the permissions is incorrect in the bootstrap/cache folder.
Easy fix: sudo chown -R www-data:www-data /myproject/bootstrap/cache
