I have noticed that in the
<html> tag on my WP site that the language is defined as US English.
<html lang="en-US" prefix="og: http://ogp.me/ns#">
I would like to change it to British English
en-GB but I'm not sure of the best way.
I dug around and found
general-template.php which makes a call to
get_bloginfo('language'). I could manually insert the value here but that doesn't seem like the best way to do it.
What is the proper way to change this value?
