Thanks for your reply!

No, I don’t use WPML. I have nonetheless added your code snippet to my functions.php, replaced all three occurrences of 'nb' with 'de' (since my site is in German) and tried again – without success. It seems that ICL_LANGUAGE_CODE is indeed not defined.

I have now tried the following:

1. I have created a fresh installation of WordPress (based on https://de.ww.wp.xz.cn/latest-de_DE.zip)
2. I have installed and activated Foo Gallery 1.2.4
3. I have installed and activated Foo Gallery Captions 1.0.2
4. I have created a new Foo Gallery with two pictures.
5. I had to save the gallery before I could edit the captions.
6. I have edited the captions (as described in my initial post).
7. I have changed the gallery template to “Simple Portfolio” (to actually see the captions).
8. I have saved and published the gallery.
9. I have created a new post and included the gallery.
10. I have published the new post.

Result: the gallery shows up in the post but the captions don’t.

Do you have any other idea what I might try? I assume it shouldn’t be an issue to have used the localized WordPress package (de-DE) for the installation, should it?

Thanks,
Chriki
