 * what is the code in comments.php of your theme, in the line with `wp_list_comments(......)`?
 * does the function `advanced_comment()` exist anywhere in your theme or in any
   activated plugin?

 * > `'callback'`
   >  ( callback ) The name of a custom function to use to open and
   > display each comment. Using this will make your custom function get called 
   > to display each comment, bypassing all internal WordPress functionality in 
   > this respect. Use to customize comments display for extreme changes to the 
   > HTML layout. Note that your callback must include the opening <div>,
   >  1. , or
   >  2.  -  tag (corresponding with the style parameter), but not the closing tags.
   >        WordPress will supply the closing tag automatically, or you can use end-
   >        callback to override this default. The callback is separate from the end-
   >        callback to facilitate hierarchical comments. Use with caution.
 * PS:
    what theme are you using and where did you download the theme from?

 * Hi [@alchymyth](https://wordpress.org/support/users/alchymyth/), thank you for
   the quick response! I really appreciate it.
 * I am using a custom theme made by someone else.
 * Where can I possibly check so can I find this function advanced_comment()? Can
   I possibly see this inside the /custom_theme_folder?
 * Please advise. Thanks!

 * The code under the custom comments.php file is :
 * <?php wp_list_comments(‘type=comment&callback=advanced_comment’); //this is the
   important part that ensures we call our custom comment layout defined above
    ?

 * to remove the error message or warning, change the line to:
 *     ```
       <?php wp_list_comments('type=comment'); //this is the important part that ensures we call our custom comment layout defined above
       ?>
       ```
   
 * if the function is not in _functions.php_ of your theme, then any further help
   through this forum is quite impossible for a custom made theme.
 * try to contact whoever made the theme for you.
