I've been looking for an answer to this question for a long time, but haven't found anything: how come when I use the_excerpt() on a given site it doesn't automatically print the first few characters of the content?
The excerpt only prints it if something has been added to the WordPress summary field of the post.
How can I fix this problem? With other sites this does not happen and if no text is added on the summary the excerpt is generated automatically.
What could it be that the excerpt is not automatically generated?
My situation is similar to this: Automatic Excerpt Not Working
but your response did not provide me with any advice unfortunately.
