XF 1.3 captcha not showing @ lost password form


not sure if this is the right place to put it but FunCaptcha is not showing on our website in the 'forgotten password' box. FunCaptcha is globally enabled in 'user registrations' option and 'Use CAPTCHA for Lost Password Form' is also ticked in 'user options' option.

The code for implementing FunCaptcha in the form seems to be broken. Any ideas how to fix that?
