Why doesn't cropping an article with the_content() function in Wordpress work?

Question

WordPress

There is an article in the text of which is <!--more-->.
Next I output the_content(); but the text is not cut off, but also displays the <!--more-->
code:

global $more;
while ( have_posts() ) : the_post(); 
  $more = 0;
  the_content( '[more..]', true);
endwhile;

Answer 1

The problem was that it was necessary to write <!--more-->in the "Text" tab, and if you write in the "Visual" tab, the text will be replaced by<!--more-->
