I'm trying to remove the buttons on the bottom of the k2 frontend editor.

Here's what I'd like to remove:

<div id="editor-xtd-buttons">

I tried adding display:none; to the css, but the css has ?v=2.6.7 at the end and doesn't read the changes I made.

If these can't be removed, how can I replace the editor with another?

thanks in advance. :)

Copy inside the content of original itemform.php
and at line 38 add this:
