Is there a maximum number of users that can subscribe to a blog? I nioticed that after a hundred or so, I started getting emails from users saying that they were receiving a fatal error from line 31 of wp-register.php
Fatal error: Call to undefined function: validate_username() in /home/not-telling/public_html/wp-register.php on line 31
and line 31 is:
if ( !validate_username($user_login) ) {
$errors['user_login'] = __('ERROR: This username is invalid. Please enter a valid username.');
$user_login = '';
}
