Attachment can't be downloaded

Exporting from backend works (with http and https).
Exporting from frontend works (with http and https).

damn...

I compared the request and response headers during accessing the file. If you are interested in, take a look in the attachments.

In the response header, there is one entry (except of the status entry) that differs:
Connection: Keep-alive

Please add the following line of code to <Joomlaroot>/components/com_jem/controller.php
Go to line 121 and insert
header("Connection: keep-alive");
before the line containing this: header('Content-Disposition: attachment; filename="'.basename($path).'"');

Hope that works...

On my attatchment-working test page it worked also with this addition. So first of all, this new line of code should not break more than before

File <Joomlaroot>/components/com_jem/controller.php updated with Keep Alive but unfortunately the result shows the same error.
Tried also with Android Windows and Linux browsers....

stefanato,
on your page I have the same problem like in this thread ( www.omco.pd.it/formazione/corsi-e-convegni/event/665-il-trattamento-della-neoplasia-del-colon-retto.html ) and another problem that you wrote in the other topic ( www.omco.pd.it/formazione/corsi-e-convegni/event/658-il-trauma-e-il-corpo.html ). Both on Chrome Desktop.

How do you force ssl? As I saw you are using Apache Webserver, so the problem may be not Nginx.


kicr and stefanato,
1. what did you configure at JoomlaBackend -> System -> Configuration -> Server -> Gzip-Compression?
I don't use gzip-compression. @jojo, do you use?
2. What happens, if you change "Report errors" on JoomlaBackend -> System -> Configuration -> Server -> from Default to Development? Do you get an error message when downloading the file?
3. Login to you pages FTB and please wrote the permissions of the event-folder containing the problematic file and the permission of the file itself.
For me its: Folder: 0755 and File: 0644

@Egnarts: I don't use gzip.
What is FTP?
