Files visible in Backend but showing "0 downloads" in Frontend after Restore

[Emanda]

Hi,

I am using jDownloads 4.0.36 on Joomla 4.4 (PHP 8.2).

I used the jDownloads Backup/Restore tool to move data from Site A to Site B (both local). While all categories and files appear correctly in the Backend, the Frontend shows the categories but reports "0 files" or no downloads available.

I also noticed some duplicated categories and user groups after the restore process. I have already tried 'Re-calculate' in the tools and verified that all items are 'Published' and set to 'Public'.

Is this a known ID conflict issue during restoration? Any tips on how to fix the link between files and categories?

Thanks!

Hi,
thanks for the detailed report.

Your setup appears to use jDownloads 4.0.36, which is quite old compared to the current 4.1.x line.
The behavior you describe (items visible in backend, "0 files" in frontend, plus duplicate categories/groups after restore) is typically caused by inconsistent restore mapping or importing into a non-clean target state.

Please first confirm:
1. exact Joomla version (your profile says Joomla 6, post says Joomla 4.4)
2. exact jDownloads version
3. whether Site B was fully clean/empty before restore

Recommended next step is to update to the current jDownloads release and retest the restore flow on a clean target.
If the issue persists after update, we can then check category/file relation mapping (catid links), asset/ACL consistency, and duplicate restore artifacts in detail.

If possible, could you also provide your jDownloads backup package (or a sanitized copy) for testing?
That would help us reproduce your exact restore scenario and verify the root cause much faster.
