* The plugin detects my theme as not being HTML5, even though the theme IS HTML5.
After a bit of digging I discovered that this is because the check you use checks
for in header.php whilst my theme had . The check
you are doing is case sensitive – but according to the notes on w3schools ([http://www.w3schools.com/html5/tag_doctype.asp](http://www.w3schools.com/html5/tag_doctype.asp))
the doctype declaration is not case sensitive. I’ve changed my header file, but
to avoid this happening to anyone else could you tweak your check so that it
is no longer case sensitive?
Thanks

it if this patch was applied.
