Delete subject, old topic

Hi there I have followed this instruction to hide “Subject” when creating a new message, but it breaks my site. are there any syntax errors in these code snippets?

You cannot get rid of it.
But you could change the Subject input type to ‘hidden’.

For example, in this file:
bp-profile-message-ux\bp-profile-message-ux.php

You could change:
$button_divs .= ‘<input type=”text” size=”41″ maxlength=”50″ name=”private_message_subject” id=”private_message_subject” /><br /><br />’;

To:
$button_divs .= ‘<input type=”hidden” name=”private_message_subject” id=”private_message_subject” value=”New Message” />

‘;

And delete the field label:
$button_divs .= ‘<label for=”private_message_subject”>’ . $subject_label . ‘</label> ‘;
