    Override

    To override this PHP function, use this hook in your child theme or plugin ("my_custom" can be changed):

    PHP
    add_filter('pre_nebula_post_tags', 'my_custom_post_tags', 10, 2); //The last integer must be 1 more than the actual parameters
    function my_custom_post_tags($null, $options){ //$null is required, but can be ignored
        //Write your own code here
    
        return true; //Return true to prevent the original function from running afterwords
    }

    You can completely disable this PHP function with a single line actions:

    PHP
     add_filter('pre_nebula_post_tags', '__return_false');
