Shareaholic plugin returns errors

When i activate the plugin, I get this error backend:

Warning: is_writable(): open_basedir restriction in effect. File(/customers/cineme.be/cineme.be/httpd.www/wp-content/uploads/shareaholic/) is not within the allowed path(s): (/customers/4/c/6/cineme.be/httpd.www:/customers/4/c/6/cineme.be/httpd.private:/customers/4/c/6/cineme.be/tmp:/customers/cineme.be/cineme.be:/var/www/diagnostics:/usr/share/php) in /customers/4/c/6/cineme.be/httpd.www/wp-content/plugins/shareaholic/sexy-bookmarks.php on line 211

Frontend the error show as well and fails to load the site completely:

When i deactivate the plugin, things return to normal.
