Hi
I've just upgraded my 6.9.5 to 6.9.7 and have discovered four instances of [type="text/javascript"] which are not required in HTML5 and can't find where to edit them out. Trying to find where the include_headers() function is.

With a little more savvy [inc/_core/template.funcs.php]
Line 1065
From
$script_tag = '<script type="text/javascript"';
To
$script_tag = '<script';
