PHP Fatal error: Uncaught Error: Call to undefined function get_theme_root()

🐞 bug report

Behavior: A customer reported the following issue occurring on their site: PHP Fatal error: Uncaught Error: Call to undefined function get_theme_root() in /<path>/vendor/freemius/wordpress-sdk/start.php:56.php

Line 56 is the following: $themes_directory = get_theme_root( get_stylesheet() );

It looks like, in some cases, function get_theme_root() might not be present when the Freemius SDK is initialised (i.e. when the plugin includes it, on load). It would be worth investigating the condition in which this occurs, so that the error can be prevented.
