    I have updated my wordpress from 4.3 to 5.4, now from some days I am getting the below error :
    PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘my_custom_fonts’ not found or invalid function name in wp-includes/class-wp-hook.php
    I have tried to look in class-wp-hook.php but does not understand what to do?
