I installed patch SUPEE 6788 and the password reset form was no longer working. I found this question and by changing the customer.xml I could restore the reset functionality. The problem is: if the user enters a wrong password (ie the password must have a minimum length of 6, but the user enters only 4 letters), there is no error message. There is a
<?php echo $this->getMessagesBlock()->getGroupedHtml(); ?>
right before the form tag, but it still doesn't show the error message. Weirdly enough, if I navigate to the login form afterwards, the errormessages that should be displayed at the resetform are displayed there.
Anyone have a solution for this?
