I am using Chrome and the latest (6.7.5) version of TCPDF and when I run the ‘I’ inline option for downloading I receive the following error: ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_DISPOSITION. If I comment out line 7734 header('Content-Disposition: inline; filename="' . rawurlencode(basename($name)) . '"; '); then the file downloads successfully.

With Firefox I receive The page you are trying to view cannot be shown because an error in the data transmission was detected.

I’ve recently downloaded my code from a dev server 7.4 to my local server 8.2 but have obviously upgraded to the latest 8.x friendly version of the code and so not sure if this is a bug or something I need to fix? (The dev server outputs fine with an older version).
