    Hi,

    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)
    ?

    Finally …. big thanks for your help !!! what is the difference between . get_category_link and. get_the_category_link?

    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:)
