Thank you for your reply.
In fact I can't find how to define the default language file.
I solved the problem by uploading the new file and replacing the old with the new one by "
uploading a new version" over the default file.
I installed a new compatible language file and it works.
But I would like to destroy the old. However it is locked.
Can you tell me how I can unlock it in order to delete it.
THANKS
No, the problem does not exist in English.
However, I don't know how to solve this problem in French.
I've been using the forum for years and never had this problem.
do you plan to tell me what i should do?
