Hello, I try to translate elements of the admin with a .txt file but some terms do not seem translatable (see https://www.hekla.ch/traductions.png).
There have been a lot of interface changes in v3 so that's inevitable. You should be able to change anything in the sidebar in the menu manager.
ok but where is the menu manager?
Under Settings. Unless you're just using Perch.
You can add the following to your config.php to help identify strings not being run through the translation system:
Can you give any further detail about the required string, because that's translating for us here.
The left menu bar with:
'My page', 'Pages', 'Forms', 'Organise', Categories', 'Assets'.
In the Edit section of a page, in the repeater module:
'Add an item'
I'm talking about the string required which you boxed in your picture.
Ah yes sorry you are right, it works for the string 'required'.
Add an item is fixed, so it's just the menu items?
Add an item
I wish i could translate item in the left menu bar too :-) Some of my clients doesn't understand english at all (that's a shame but that's a fact..)
Right, so just the menu items.
