 * Can You please paste that code again putting it in backticks?
    Right now it’s
   a little bit messy here.

 * Hi,
 * Well, the piece of code in question is:
 *     ```
       <?php
               $categories = get_the_category( );
               $separator = ", ";
               $output = '';
   
               if ($categories){
                   foreach ($categories as $category ) {
                    $output .= '<a href="' . get_the_category_link($category->term_id) . '">' . $category->cat_name . '</a>' . $separator;
                   }
                   echo trim($output, $separator);
               }
       ?>
       ```
   
 * Have You tried to use :
    `get_category_link($category->term_id)` instead of: `
   get_the_category_link($category->term_id)` ?

 * Well…
 * Main difference is that get_category_link exists and get_the_category_link do
   not.
 * I do that same mistake at least once a month:)
