Update
Fixed by setting Global Configuration > Frontend Configuration > Download Sequence > "Use Downloads title as download link" to "Yes"
It was set on "No" and after setting on "Yes" it immediately allowed public users to download files that were previously set to "Only registered and logged-in users can download this file." ....the issue below in the original post.
I set it to "No" again to try and replicate the issue, the interference to allow public downloads settings as described below didn't return.
I'm not sure if a couple of tries to reset both Categories and downloads permissions and in the Tools section also helped.
I can tell you when I did reset they had no effect on the issue below.
However, selecting "Use Downloads title as download link" to "Yes" was instant and the download button appeared.
This issue affected all downloads on the site, that site was always public and I think the issue started when updating to Ver 3.9.8.4
That's when I also noted the download link in the download title disappeared.
I can't remember setting that to "No" at anytime...its always been yes.
Original post before the above "fix"....
This is weird, Here is an example download.
https://sturmbot.org/index.php/downloads/download/2-sturmbot-for-steam-packages/67-sturmbot-1-9-for-steam-dod-versionThe site is set to allow public downloads just as it says in the tutorial.
At some point on an update it seems to have broken.
https://www.jdownloads.net/documentation-for-v3-9/access-user-group-permissions-v3-9/an-initial-view-of-permissions#public-siteOn that page (Public Site) it shows you click the Downloads option to "Allowed" and all is good.
My settings are the same, Downloads set to "Allowed" but as you can see on that sample link of my site it says...
"Only registered and logged-in users can download this file."
I have even gone into the categories and ticked allowed there as well, nothing works.
I have also tried to reset both Categories and downloads permissions and in the Tools...
https://www.jdownloads.net/documentation-for-v3-9/access-user-group-permissions-v3-9/an-initial-view-of-permissions#recovery-or-startagainThat too, did not work.
My settings screenshot is attached.
This is jDownloads Version 3.9.8.6, problem was also on jDownloads Version 3.9.8.4 and updating made no difference.
Any hints ?
Thanks.
