I have an Oracle Apex Application, 
I need the application to be in French. I set the language in Application Primary Language as French (See screenshot) and Application Language Derived From Application Primary Language.
Most of the default messages are in now in French but few of them are still in english. For example If I have a page item with a validation check. Let's say ItemX should be between 0 and 10, if the validation fails, I got the message in english saying : ItemX is not between the valid range of 0 and 10.
Does anyone know how to solve that please ?
Thanks. Cheers,
