If you are looking to customize the post info, such as removing the date of the article or the name of the author, there are a couple of options available.
First, you can completely remove the post info function, by adding the code below to your functions.php file.
But, if you want to remove only the date for example, you can add this filter and remove [post_author_posts_link], [post_date] or [post_time], based on your preferences.
When you add this code, make sure that there are no other functions that add similar functionality.
