    Hi, just update to PHP 8.0 and I’m seeing the following errors on the dashboard page and website in admin, please can you help? I have tried deactivating theme and plugins. Theme is Ocean WP with Elementor.

    I would look at your navigation menu. I looks like it sending a null value for some reason. The error “cannot modify header” happen when the browser thinks the header was sent. This is usually caused by an error that occurred earlier. The first error is complaining about a value being empty.

    Thanks for the help. I found one error but still getting the messages although it does disappear now when I deactivate woocommerce.
