When I open admin page for WPmail there is only white page.
The logs:
PHP Fatal error: Call to undefined function WPMailSMTP\Admin\wp_json_encode() in /path-to-site/wp-content/plugins/wp-mail-smtp/src/Admin/Area.php on line 138
Wordpress 3.8.27
PHP 5.6
php5-json (installed and enabled)
What’s the problem?
