Undefined array key 0 in DisplayManager.php on line 79

  • I have a website that wasn’t updated for too long, now I performed all updates (WordPress 6.6.2 using theme Twenty Seventeen).
    On the gallery page, I get this warning:
    Warning: Undefined array key 0 in /customers/9/0/a/rodewinter.be/httpd.www/wp-content/plugins/nextgen-gallery/src/Display/DisplayManager.php on line 79

    I have disabled several plugins to find out if there is interference but without result.
    Any idea?

    The page I need help with: [log in to see the link]

    Additional info:
    It might have something to do with the WP Multilang plugin: The site uses 2 languages and in the Gallery setup I used [:en] and [:nl] to create different gallery titles in English and Dutch. That worked before the upgrade, but now I see for example [:nl]Kleine Mythes[:en]Tiny Myths[:] in stead of just Kleine Mythes in Dutch…

    Hi @vasch,

    Thanks for reaching out,

    Upon checking the gallery frontend page from my end, it looks fine without any error or warning message. For your confirmation, please refer to the screenshot here.

    Could you please confirm if the error appears on your end or not, and I will get back to you accordingly.

    Thanks!

    I have found the reason for the php error: an old page that contained the old code to show the gallery. Removing that and using the correct block solved the php error.

    However… the translation problem of the gallery titels – using WP-multilang – remains. I had to remove the [:en], [:nl] and ending [:] of the 2 used languages in the gallery titles and replace them with a bilangual title such as “DuchName | EngName” . The titles of pictures is ok, only the gallery.

    But maybe that’s for another subject?
