TCPDF ERROR: Some data has already been output, can't send PDF file

is the message I get when clicking on the "Download" link on the "Manage Email Reports" page.

The URL is
index.php?module=API&action=index&idSite=2&period=week&date=2011-03-24&updated=2&token_auth=1234&method=PDFReports.generateReport&idReport=1&outputType=1

Sending it via email works.
mod_php 3.5.6 + mod_security

Keywords: PDF
