SEF ADVANCE doesn't modify virtuemart URL

If you go to :
www.myusbshop.fr/index.php/virtuemart?pa...tegory_id=9&TreeId=2

You will see that SEF ADVANCE doesn't modify my products URL.

What I've done :
- Installing component
- replace .htaccess
- installing plugin to component/com_virtuemart
- activate legacy.
- activate SEF advance
- activate Search Engine Friendly URLs

Best regards,

Antony

SEF is not activated here at all. Make sure you activated SEF in global configurations.

Thank you emir.
I've connected it. but virtuemart URL rewriting is still down.

SEF Advance is still not active, only the core SEF. Check that SEF Advance is activated and check your about screen for the license.

uninstall and reinstall.
Everything is working !!
Thank you emir !
