We've got a DNN-implementation based on version 4.02 .

We've internationalised it successfully to Dutch ("nl"), French ("fr") and English ("en"). However, now we need to have "nl-NL" (Dutch - Netherlands) in addition to "nl". The problem is that I don't get any resx-files with 5-letter language-codes to work. In case of "nl-NL" it keeps defaulting to "nl".

• I've checked our custom-code for anything that may cause this

• I've tried adding a new language with a 2-character language code (Czech, "cs") . Works fine. Then I tried to add it as "cs-CZ" instead and it defaults to English.

• Thread.CurrentThread.CurrentCulture and -CurrentUICulture are correctly set to "nl-NL" .

• I've scoured the DNN-source localization library for a reason, but I can't find anything.

• I can edit the "nl-NL" files from the Admin/Host menu just fine. Same goes for creating language packs.

So my question is: is this a known problem? If so, would upgrading DNN help, or is there a solution? Is there a setting I missed?

Feel free to point me to older threads if I've missed them.

Cheers.

Thanks for the answer.

I'm afraid updating is just not an option for the time being. (Though we should, probably).

I've tried changing every single resx-file to a five-character code. Didn't work. They all defaulted to the "default-resx" afterwards. Reinstalling the languages from the host/admin menu didn't help either (I was hoping for some mystical setting that would change, but sadly: no).

So, I'm very sorry, but it didn't change a thing.
