undefined error

[iyoua]

After I upgraded webtrees from 2.1.4 to 2.1.5, the faces module (v2.7.1) will not work. Open the photos in the faces tab, and undefined will be displayed on the right.
Why?

You can also find previously set pictures and individuals in the control panel.

I have the same problem at my webtrees test server. No chance to add new "faces". When I open a photo it shows always "undefined".

I found that a file in the Vandor folder may have been upgraded so that faces cannot read the setting data. The solution is to copy the Vandor folder of the previous version of webtrees to the new version as a whole, and faces can be displayed normally.

Please check webtrees logs in admin. Seems it's can contain error. Also please post response from Chrome Dev tools.
