Hello
I have migrated a wp website to my digitalocean server and when I go to admin panel > header builder and trying to save it gives me an error:
PHP Fatal error: Uncaught TypeError: ftp_nlist(): Argument #1 ($ftp) must be of type FTP\Connection, null given in /var/www/mobshop/wp-admin/includes/class-wp-filesystem-ftpext.php:420
