I was using PhpExcel 1.8.0 for quite a long time.
Now I had to change my Webspace-Provider und there PhpExcel is not working any more.

The PHP-Version is the same (5.3), but also the same problem with 5.6.

In the errorlog I can fing this:

Mon Dec 28 15:05:00 2015] [error] [client] PHP Fatal error: Uncaught exception 'PHPExcel_Writer_Exception' with message 'Could not close zip file php://output.' in /is/htdocs/wp12468360_2MA22PO950/www/kgvtest/classes/phpexcel/Classes/PHPExcel/Writer/Excel2007.php:400nStack trace:n#0 /is/htdocs/wp12468360_2MA22PO950/www/kgvtest/mitglieder/mitglieder_export.php(152): PHPExcel_Writer_Excel2007-]save('php://output')n#1 {main}n thrown in /is/htdocs/wp12468360_2MA22PO950/www/kgvtest/classes/phpexcel/Classes/PHPExcel/Writer/Excel2007.php on line 400

Does anyone has an idea what is going wrong here?
Thank you!
