No "buy now" button or quantity

Where to switch on the buying option. looks like my testshop does not display something necesary;)

http://haus-der-stille.ro/shop/

Any sugestions?

Someone has removed the buy button code and has replaced it with a contact us code.

div id="cartAdd">
<a href="http://haus-der-stille.ro/shop/index.php?main_page=contact_us">Contactati-ne</a>

Open an unaltered tpl_product_info_display.php and replace the altered code.

Or, this sounds like you have setup your Store Status as Showcase Only ...

Where did you find that file?
The file I found in /shop/includes/templates/template_default/templates/
contains this:

?>

<div id="cartAdd">

<?php

  echo $display_qty;

  echo $display_button;

Anywhere else?
When I set the store status to "0" normal store, then the whole store disappears.

Strange enough, after 2 minutes the store is OK and now I do have shopping cart and buy now button.
