Thank you! Simple but crucial question : are these lines errors stopping the plugin from working properly, or can they just be ignored?

Thank you so much for your help… that is amazing! So, I have tried to unable all plugins (except Woocommerce and Sumup of course), and change theme, but I still have the problem. I haven’t mentioned that I am using Elementor and Elementor pro (which I both disabled for test purposes), and that everything has been built through that.

I opened the three files the errors notify and the concerned lines. Here they are :

In the wp-admin/includes/misc.php file :
header( sprintf( 'Referrer-Policy: %s', $policy ) );

In the wp-includes/functions.php file :
header( 'X-Frame-Options: SAMEORIGIN' );

In the wp-admin//admin-header.php file :
header( 'Content-Type: ' . get_option( 'html_type' ) . '; charset=' . get_option( 'blog_charset' ) );

I have never changed the php.ini file, but I can call the host for guidance, if this is the only way through.

Do you have any idea of what could be happening with the lines cited above?

Thank you so much for your help.
