Why can't I edit the include area?

Question

Why can't I edit the include area?
I created the files
I connect like this:

the code

<?$APPLICATION->IncludeFile(
    DEFAULT_TEMPLATE_PATH."/include/address.php",
    array(),
    array("MODE"=>"html")
);?>

everything is displayed on the site itself, but when you try to edit through the edit mode, when you click "Save", an error appears: "Error creating file."
there are already previously created files nearby - everything is fine with them, everything works.

Check the file permissions on the server.
