About the edit form on frontend, as I mentioned, the template doesn't override this form so I renamed this file: /templates/gk_rockwall/html/com_content/form/edit.php
but you have this custom css code in override.css file of template on your site which hides all content of edit form:
div.control-group { display : none;}
which will hide all elements having this control-group class, I recommend you to not use this code. Pls remove it and you will see the normal edit form.
