Hi, I have recently installed the wordpress and I can′t send comments in my post, when I make click in button “send the comment” the page is in white whit the direction “https://thenameofmyblog.com/wordpress/wp-comments-post.php”. I haven′t any comment in my post becasuse I have deleted the comment the blog includes by default, anybody knows what is happen with this? Many thank!
