[gianlucab81]

i have a problem when using virtuemart under joomla..if i browse under sub-category the logo image that is always shown in page can't be found because the address is changed in website.it/category/subcategory/logo.jpg

i have this problem only when browse virtuemart articles/category

how can I avoid this?

Thanks!
