valwp

In both situations.
WP-Members return two PHP warnings when the user is unconfirmed by an admin and when he doesn’t click on his validation link sending by mail :

Warning: Undefined array key "acct_not_approved" in /var/www/wp-content/plugins/wp-members/includes/class-wp-members-dialogs.php on line 221
Warning: Undefined array key "acct_not_validated" in /var/www/wp-content/plugins/wp-members/includes/class-wp-members-dialogs.php on line 221

These warnings are returned after the submission of reset password form with an ID that existing in users list.

When the new user is validated but still not approved by an admin, the reset password form return only one warning :

Warning: Undefined array key "acct_not_approved" in /var/www/wp-content/plugins/wp-members/includes/class-wp-members-dialogs.php on line 221

When the user is approved and validated, the reset password form is working normally.
