User registration email with link to generate password - link error.

[ibrythill]

Link to generate password is surrounded by "<..>". In most Poland email hosting, the last ">" is detected as part of the link. When follow this link, the user name is not being recognised and password isn't generated.

To fix that, in pluggable.php change line 1741:

$message .= '<' . network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user->user_login), 'login') . ">\r\n\r\n";

to this:

$message .= network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user->user_login), 'login') . "\r\n\r\n";
