Thanks for your answer… I was just adding a code for a stupid button that I found on a forum (I don’t know a lot about coding so I just copied it into fonctions.php)… But afterwards, by accessing via filezilla, I deleted exactly the code I had added before… So in my opinion the functions.php should be back to what it orginally was but doesn’t seem so as the white screen + parse error are still there…
Do you have any idea how to find a solution?
