Hi Cajuna. If you’re referring to the post listing on the home/blog page, that uses the excerpt, which is either the number of words you specify from the post content or, if you enter one, a defined Excerpt in the section below the post content in edit mode. If you want to use the “More” tag you need to edit the content-related theme files to use the_content() instead of the_excerpt(). If you just want the excerpt to end with “Read more” you can do that with a function in a child theme.
