no validation button

responsive sheffield blue template last version zc 1.5.6a

Hello
Since update , I have no validation button in the "checkout confirmration" page, the last one : https://www.ios.fr/index.php?main_pa...t_confirmation

I have the code in the source :
?>
<div class="buttonRow forward"><?php echo zen_image_submit(BUTTON_IMAGE_CONFIRM_ORDER, BUTTON_CONFIRM_ORDER_ALT, 'name="btn_submit" id="btn_submit"') ;?></div>
</form>
<div class="buttonRow back"><?php echo TITLE_CONTINUE_CHECKOUT_PROCEDURE . '<br />' . TEXT_CONTINUE_CHECKOUT_PROCEDURE; ?></div>

but nothing appear

And the left column and the bottom of the site don't show...

some help ?

Looks like a partial white page. This means a debug file has been created. Look in your logs folder and paste the contents of the latest file (Minus sensitive data) here on the forum, between code tags.
