After installation of open hotel, it is showing in the home page -

Warning: file_put_contents(temporary:///.htaccess) [function.file-put-contents]: failed to open stream: "DrupalTemporaryStreamWrapper::stream_open" call failed in file_create_htaccess() (line 502 of E:\Website\TEST\Openhotel-sample\includes\file.inc).

Please help me to correct this error.
