Commenters redirected to admin dashboard instead of comment

Thank you for the tip! I’ve fixed the issue temporarily on my site too ??

Just to be clear, all you did was edit and add this

add_filter( 'allowed_redirect_hosts' , 'my_allowed_redirect_hosts' , 10 );
function my_allowed_redirect_hosts($content){
	$content[] = 'blog.example.com';
	$content[] = 'codex.example.com';
	// wrong: $content[] = 'https://codex.example.com';
	return $content;
}

to wp-config.php?

Precisely.

Any updates planned before I get too committed using this? thanks.
