I’ve had trouble with seeing any errors on forms etc. so I added both placeholders just to be on the safe side:
<div class="wlpeMessage"><p class="wlpeMessageText">[+wlpe.message.text+][+wlpe.message+]</p></div>
and things started to come through a little easier.
Not much help but its what I found this evening.
Nice work Scotty.
