The log shows this error:
Warning: Cannot modify header information - headers already sent by (output started at /var/www/htdocs/includes/bootstrap.inc:1391) in drupal_send_headers() (line 1243 of /var/www/htdocs/includes/bootstrap.inc).
-every time a user tries to access a private, protected file. It does not matter if the user has access to the file or not, the warning comes every time.
Several issues of this nature have been reported, but I've been unable to find one that deals with private files. Does anyone have an idea what this is all about. The functionality is not affected.
