quantity buttons controls error

quantity buttons controls error

Hi,

i have a problem with the plugin, that i bought from you.

https://www.webdesigner-profi.de/joomla-webdesign/shop/plugins/quantity-button-controls.html

After installation i get this error:
500 - Too few arguments to function plgJshoppingProductsQuantityControls::onBeforeDisplayProductListView(),

If i turn off the plugin, no css in the cart.

<div class="jshop">
<form action="/termekkategoriak/refresh" method="post" name="updateCart">
<table class="jshop cart">
<tr class="table-header">
<td width="9%" class="js_img">
Fotó </td>
<td width="25%">
Megnevezés </td>
<td width="15%">
Darabár </td>
<td width="15%">
Mennyiség </td>
<td width="15%">
Összeg </td>
<td width="10%">
Eltávolít </td>
</tr>

Please help me.

Thank you!

Zsolt
