Hi Stasweb.

this link: new.lik-astana.kz/index.php/informatsion...1&productsublayout=0 will work.
The problem doesn't have to of our module. it can the cause of Joomla or Vituemart component

There is here a material corrective
/manufacturer/?categorylayout=0&showcategory=1&showproducts=1&productsublayout=0
this problem on an example of the module breadcrumbs
go to: mod_breadcrumbs/tmpl/default.php
Adding: $item->link=str_replace( 'manufacturer/?categorylayout=0&showcategory=1&showproducts=1&productsublayout=0', '', $item->link);
Will:
echo '<li>';
if (!empty($item->link))
{ $item->link=str_replace( 'manufacturer/?categorylayout=0&amp;showcategory=1&amp;showproducts=1&amp;productsublayout=0', '', $item->link);
echo '<a href="' . $item->link . '" class="pathway">' . $item->name . '</a>';
}
something like this. There is the same problem as the link is very similar but the unit is turned off bread crumbs on the site.
What about this say your developers.
