Ok, so it must have partially been browser cache -- did the flush in another browser and though I do not get an error now when creating a field (any field) it 'saves it' upon clicking, but doesn't create the field.
I can edit the content on the page, the submission message, but do not see any form in the admin -- I do see a submit button and a random field ... attached is a screenshot of the front end, and this is the parsed code below:
<form id="Form_Form" action="/new-userdefinedform/Form" method="post" enctype="application/x-www-form-urlencoded">
<p id="Form_Form_error" class="message " style="display: none"></p>
<fieldset>
<legend></legend>
<input class="hidden" type="hidden" id="Form_Form_Referrer" name="Referrer" value="http://my.domain.com/contact-us/" />
<input class="hidden" type="hidden" id="Form_Form_SecurityID" name="SecurityID" value="768714866" />
<div class="clear"><!-- --></div>
</fieldset>
<div class="Actions">
<input class="action" id="Form_Form_action_process" type="submit" name="action_process" value="test" title="test" />
<input class="action nolabel" id="Form_Form_action_clearForm" type="reset" name="action_clearForm" />
</div>
</form>
Again, running 2.3.2-rc2
