Error in Admin

Version 2.03

I have this code in functions.php

add_action( 'wp_head', 'my_google_opt_out' );
    function my_google_opt_out() {
      if ( ! has_consent( 'analytics' ) || ! is_allowed_cookie( '_ga' ) ) {
        ?>
        <script>
          window['ga-disable-UA-XXXXX-4'] = true; // Don't forget to replace X for your actual UA numbers.
        </script>
        <?php
      }
    }
   

Not only does it block _ga but also all the similar tags -gat,_gat,_gid,_gid

In addition when I allow it in the front end it is not activated, nor are any of its “siblings”

I can’t recall the last time that I got so sucked into a plugin, interesting.
