I find it easier to just edit the header template.
This will hide the
Help and Add the
Forgotten Your Password?
Code:
<vb:comment><li><a rel="help" href="faq.php{vb:raw session.sessionurl_q}">{vb:rawphrase help}</a></li></vb:comment><li><a href="login.php?do=lostpw{vb:raw session.sessionurl_q}">{vb:rawphrase forgotten_your_password}</a></li>
Then change the language by:
vBAdmin --> Language & Phrases --> Search in Phrases --> Search for Text--> Forgotten Your Password
Enter your Words/Text in the Translation then Save
