I updated a pdf file through ftp, but on the website, after I click on the link it still shows up as the old version.
I thought it's a cache thing, as on my mobile it is shown correctly.
But I've deleted my cache and tried several browsers, but the problem persists. Even the client sees the old version still.
I've tried renaming the file on the server and changing the a href link in html as well...
What could the issue be ?
