I had problems displaying PDF files with Internet Explorer + Acrobat Reader in Microsoft Windows (Mozilla in Linux works).
Standard behaviour: click on PDF -> file is displayed in Expolorer window.
OJS behaviour: Explorer asked what I want to do with this file (Open, Save...) If I chose Open, Acrobat Reader is launched (in new window).
Acrobat Reader tried to open file, but it only displayed error "File Not Found"!
Here is my solution:
I changed one line in include/getdoc.php
header("Content-Disposition: attachment; filename=\"...
I changed to:
header("Content-Disposition: inline; filename=\"...
It works now.
(I looked on headers from http://www.math.washington.edu/~ejpecp/
- site which displays PDF well)
Does Internet Explorer displays your PDF files? Should I change 'attachment' to 'inline'? Or it is only problem with my web-server?
