Page language code is not valid
Why it matters
A language code that does not exist is ignored, so assistive technology falls back to guessing.
How to fix it
Use a valid BCP 47 code such as en, en-GB or fr-CA.
<!-- Before -->
<html lang="english">
<!-- After -->
<html lang="en-GB">Read the W3C guidance: Understanding 3.1.1 Language of Page.
