Problem for creating Australian language > leads to server errors when i go translation

[superskyman100]

Prestashop 1.7.5.1

Theme warehouse 4.2.1

Site : sexy-cherry.com (login : prod     psw : prod)

 

Hello,

I've just created one 'Australian' new language from scratch cause of certain market specificities (there is no Australian language package, and i can' tweak the existing UK or US already existing languages by just changing ISO codes)

i need the 'au' extension for my links (ex : sexy-cherry.com/au) to make it clean and clear (i guess ISO code makes it like that)

 

 

The problem is that when I go 'translations', trying to translate any theme or module, it returns a server error, here debug mode

 

Anyone has an idea how i could solve this problem ?

 

Thanks a lot
