Good afternoon, I upgraded an Umbraco instance I have to 17.3, now I am unable to select a folder with a media picker that only allows folders to be selected.
I have another site running 17.2 and I am still able to do this.
This is a known regression tracked as issue #21885 on GitHub. The fix was merged on March 3 and is included in the official 17.3.0 release notes, so it should be in the final build that shipped on April 2.
A couple of things worth checking:
Confirm your exact version — make sure you’re on the final 17.3.0 and not an RC build, as the regression was present in the RC previews.
Check your data type config — if your picker has allowedContentTypes set alongside the folder-only filter, there’s a known edge case where folders can still be rejected.
If you’re on the final 17.3.0 and still seeing the issue, it’s worth opening a GitHub issue with your data type configuration so the team can take a look.
You may want to post that in the GitHub issue tracker as it sounds like the same issue, even though it was supposedly fixed in 17.3. Does the same happen for you in a clean instance? What version did you upgrade from? Any further information could be helpful in diagnosing.
