Undefined Registration function in MS — at Version 1
|Reported by:||filosofo||Owned by:|
Description (last modified by filosofo)
Several global multisite functions, defined in wp-includes/ms-functions.php, call WP functions (such as username_exists) that are defined in wp-includes/registration.php and hence are not defined by default in wp-includes/ms-functions.php.
Patch includes the required registration.php file where needed if not already included.
