and comment out this part
<div class="ow_chat_subject_block">
{input name='subject' class="newMessageWindowSubjectInputControl"}
</div>
and then youll have to go over to the controller and make the field not require
ow_plugins/mailbox/classes/new_message_form.php
comment out these three lines
$requiredValidator = new RequiredValidator();
$requiredValidator->setErrorMessage( $language->text('mailbox', 'subject_is_required') );
$subject->addValidator($requiredValidator);
then clear your cache and you should be ok... let me know please if it works thanks :)
remove:
<div class="ow_mailbox_subject_block" id="conversationSubjectBlock">
<span class="ow_mailbox_subject_text" id="conversationSubject"></span>
</div>
Result:
But I can't seem to find how to remove "subject: undefined" on the left hand side
However still one more 'undefined' in the console drop-down to get rid off. How do I go about it?
