Chrome, pdf display, Duplicate headers received from the server

Question

I have a section on a website where I display a pdf inside a light box. The recent chrome upgrade has broken this displaying:

Error 349 (net::ERR_RESP

Answer 1

Had this problem today. Per roryok and others, the solution was to put the filename in quotes.

Previous, Chrome FAIL:

header("Content-Disposition: attachment; filename=$file");

Current, Chrome OK:

header("Content-Disposition: attachment; filename='$file'");

Note the quotes around $file.
