Attachment can't be downloaded

Hey kicr,
did you tested that?

Now we need to investigate why this problem occurs.
Eventually you server itself already runs gzip compression? So Joomla would compress it a second time?

Disabled many plugins but until now I have not found the "guilty"...
I'll continue to check and I'll advise you asap.
Thanks

If you rename the corrupted pdf files to .html, and open them in a browser, you will see the template.
So maybe something around your template extension/module/plugin forces those problems.

Eventually you could use a download component like Phoca Download to test, if those files are also corrupted.
If yes: The problem is definitly your page, if no: there may be a conflict between JEM and your page.

Which template do you use?

Hi.
Installed Phoca Download : www.omco.pd.it/phoca.html
it works correctly.
The template is JM Job Listings (joomla Monster)

I'm using a yootheme Template. Downloading pdf files through jdownloads or as download links works correctly.

When i disable the joomla gzip compression, this test page varvy.com/tools/gzip/https://varvy.com/tools/gzip/ says it is still compressed with gzip. Thats weird.

@kickr
insert in .htaccess to disable gzip

@Egnarts
i have recreate a test site here : dev.stefanato.com/formazione/corsi-e-convegni/event/679-medico-di-campo-diritti-e-doveri.html
I changed template with protostar, but the situation remains the same. I'll try to remove all plugins....
