<span class="ow_attachment_btn"><span class="ow_button"><span class=""><input type="button" value="Send"></span></span></span>  

     
And then the outerhtml

<div class="clearfix comments_hidden_btn" style="display: none; overflow: visible;">        <span class="ow_attachment_btn"><span class="ow_button"><span class=""><input type="button" value="Send"></span></span></span>        </div>

It gets changed from display:none to display:block when you click on it, so you might try playing with the custom css in admin to see if you can force the default of display:block

There is also ow_comments_input

but im not good with css so i cant help much, sorry





 

Thanks to you pretty easy fix:

.form_auto_click .ow_submit_auto_click{display:block !important;}
