All in admin in SEF Advanced may be correct and I don't have any error but my SA not work, only work SEF of joomla. If I deactivate SEF of Joomla url go to non friendly.

Make sure SEF Advance plugin is installed and published. I suggest you uninstall both the component and the plugin and then reinstall the component.
