I guess I have done everything to get the widgets running in my album using the FancyBox skin. See here: https://www.hornbill.de/Reisebilder/index.html
The album is listed on my profile page, the widgets are activated in the software and in Fancybox, but nothing is to be seen. Does anyone see my mistake?
This is a skin bug. The FancyBox skin indicates that it supports jAlbum widgets, but the skin lacks the proper setting to invoke them. You can fix this yourself, but the skin developer needs to address this.
Launch jAlbum and choose the FancyBox skin. Now choose Tools, Skin developer, Edit skin properties. In the window that opens, check autoWidgetInjection, then Save. Now open your album project again, make the album again, and upload it again.
Correction: It appears that, for reasons unknown, this skin requires its own setting for invoking widgets, rather than using the jAlbum core functionality. So, go to FancyBox > General, check Allow widgets, and make and upload the album again.
Thanks a lot! Activating autoWidgetInjection was the solution! (see attached picture). I just wonder how other albums worked with Fancybox and widgets from the very first moment without activating this option before. See https://hornbill.de/Vehikel-Bilder/
Anyway, thank you and all the best!
