Fatal error: Call to undefined function maybe_hash_hex_color() in /web/FIFTHANDGRAPE/wp-content/themes/hueman/functions/ on line 108dynamic-styles.php <snip>
Googling reveals that ever since version 3.4 (long before the 4.7.5 I have installed), this function was moved from a "customizer" file to wp-includes/formatting.php (such as per the documentation at https://developer.wordpress.org/reference/ ).functions/maybe_hash_hex_ color/ But when I look in that file, there is no "maybe_hash_hex_color".
