PHP Fatal error: Uncaught Error: Call to undefined function get_bloginfo

Hi,

I think there is a bug when Direction is RTL in themes,
I get many of these errors these days on our hosted wordpress web sites using PHP 7.1

Sample stack trace:

PHP Fatal error: Uncaught Error: Call to undefined function get_bloginfo() in /home/username/public_html/wp-includes/class-wp-locale.php:233
