I'm trying to update my translation to Portuguese (Portugal) [pt_PT], but the menu option 'Translate UI' doesn't respond.
If I try to get it from here:
I get a 404 error.
Could you please tell me where can I make the update, so it may be available for future versions?
Thanks in advance

I found the source code via NetBeans technique, and there are two similar message files, pt-PT and pt_PT.
I think they are the same, but if they aren't, one of them should be renamed.
To edit the translation this way, I would need to know which is the correct one. Officially, it should be pt_PT.
Can I change it in NetBeans and send it from there?

Hello,
Good evening,

I have just corrected the error for the menu without effect. The source file is now on Framagit, at the following address:
https://framagit.org/ostorybook/mainApp/-/tree/master/src/i18n/msg
It is the one ending with pt-PT.

Sorry, the file is in fact "messages_pt_PT.properties".

There were several other anomalies. This has been corrected.
