We recently switched from Kirby 2 to the latest version. Great job to the whole Kirby team!
However I ran into a strange issue. The contents from the site.de.txt are not displayed correctly, but only if a page from from the first directory level.
Sorry, I wasn’t precise. I just took two different examples, but they produce the same issue. They are basically reading different text parts from the source file site.[lang].txt
In the meantime I am not that sure anymore if the issue really come from the site.txt. The reason is the different behaviour when calling the pages from our website:
So it is basically only the first folder level with produces the Wong language in the footer. Fun fact: all other contents are in the correct language.
The question is if all these different pages really use the same code in the footer/the same footer. All I can offer is to have a look at your project, this is probably one of those things that are obvious if you see what is happening but hard to debug from remote.
