Hi everybody,
I have the following error on my website, only with Chrome, and only since they change the version 2 months ago :
“error on line 1 at column 39: XML declaration allowed only at the start of the document” (see screenshot).
I don’t see anything wrong in my html (if I look at the code in another navigator, say Mozilla, here is how the code starts :
<!DOCTYPE html><html lang="fr"> <head>
<meta charset="utf-8">
<title>....
I suppose something is send to Chrome before the start of my HTML? How to know what is sent prior to my html?
It’s on every page of my website so I think maybe it has something to do with the following files : index.php, webroot/index.php, core.app, bootstrap.php, AppController.php.
But I haven’t found the problem so far, and I’m loosing traffic…
Please help if you have any idea…
