I was trying to change the privacy message that's displayed when you register. It should be the default_privacy field. I copied qa-lang-options.php to my language folder, en-GB and put this:
'default_privacy' => 'NEW PRIVACY',
However, this didn't override it. My language in the settings is en-GB (and some other lang files are overriden just fine.
But then I changed the original value in qa-include/qa-lang-options.php and it still doesn't change! What is going on here?
