Hi templateinvaders,
Thanks to further investigation from our side :
We found this :
$config_file = tinvwl_scan_dir( dirname( dirname( dirname( getenv(‘SCRIPT_FILENAME’) ) ) ), ‘wp-config.php’ );
$load_file ? = tinvwl_scan_dir( dirname( dirname( dirname( getenv(‘SCRIPT_FILENAME’) ) ) ), ‘wp-load.php’ );
To add on the api/ajax.php files.
