Can you try creating a phpinfo file?

<?php

// Show all information, defaults to INFO_ALL
phpinfo();

// Show just the module information.
// phpinfo(8) yields identical results.
phpinfo(INFO_MODULES);

?>

Call that and see whether you're having problems with PHP after the install.

Thanks for ur reply. The roundcube one works now, but only without https. But another problem is back. The email function dont work on my phone.

It works to receive mails, but not write mails on Android, but on iPad (iOS) everything works. Why? Weird...
