COOKIEPATH

Hello,

Plugin results in error:
PHP Notice: Use of undefined constant COOKIEPATH – assumed ‘COOKIEPATH’ in …/wp-content/plugins/wp-cerber/cerber-load.php on line 737

Yes, my site is multilingual.
After recording in the wp-config.php: define(‘COOKIEPATH’, ‘/’);
the errors are as follows:
PHP Notice: Constant COOKIEPATH already defined in …public_html/wp-config.php on line 95
PHP Notice: Use of undefined constant COOKIEPATH – assumed ‘COOKIEPATH’ in …/public_html/wp-content/plugins/wp-cerber/cerber-load.php on line 737

WP 4.9.4
WP Cerber 6.5
PHP 7.1

Best regards.
