Check if you uploaded all files.

Thank you for your answer !
I just checked if I miss a file but it seems not. the only files I have selected, it is in the language file, I only kept the english and the french 2 files.
Which one do you think may have been forgotten ?

Yes - just extract all files and upload them one more time
