The virtuemart extension for artiosef creates a lot of url in the articles example: about-us/product-name and i don't know why create this url under about-us.
Thank you for your support

Hi,
The first part of URL depends on the Itemid stored with it, so for some reason your VirtueMart uses wrong Itemid. Make sure that you have at least one menu item pointing to VirtueMart's frontpage, so VM can use correct Itemid. Or go to JoomSEF -> Manage Extensions -> VirtueMart -> Common and set "Itemid handling" to "Override" and "Override Itemid" to the preferred VirtueMart's menu item ID.

thank you very much. I resolved this problem.
