I have the following problem with the recovery link.
I send it to gmx and that was the link.
recovery/activkey/cdf0bf3b5e2ae9b8ebbbe0fb16b3b97b/email/klaus.mergen%40gmx.de.
The problem was the dot on the end of the link.
The bug comes from RecoveryController.php line:50
$message = UserModule::t("You have requested the password recovery site {site_name}. To receive a new password, go to {activation_url}.",
When I hack the code and delete the dot it runs.
