Undefined array key 0 in DisplayManager.php on line 79

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…

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?

Hi @barsha05,

The theme is Twenty Seventeen, a standard WP theme. I have tried some other default WP themes and all give the same result.
With the last test, I entered the name of the gallery with language tags ( for ex. [:nl]Portret[:en]Portrait[:]) and when saving, I see the name as “Portrait”, even in the Dutch (nl) admin page and on the front-end website. Sometimes however, it appears as “[:nl]Portret[:en]Portrait[:]” .
This is documented with the schreenshots in this link.

Changing the album name or the picture titles in the same way works fine.

When looking in the DB, I do see the original names (eg [:nl]Portret[:en]Portrait[:]) for picture and gallery names.

Hope you can help me!
