Check for and remove any white space from the beginning of the file.

Otherwise you may need to upload a new file and ensure it has been saved as UTF-8 without BOM.
I recommend using a proper editor such as Notepad++

Thank you, it's ok now, not a withespace problem, I don't understand this error, maybe an error of encodage or filezilla data corruption ?
I have remplaced the file by the default file and it's ok now.
