Hello John,

Thank you for your quick response and assistance you want to make me!

First I would like to finish congurer all and then I come back to you ...

For further information:
I did not "alias SH404SEF" (for the moment). I only "alias JOOMLA!"
I have not duplicated link. I just have a difference between the links "native joomla" (which are in the sitemap generated JSitemap) and links generated by SH404SEF. As I have explained to you in my previous post.

I understand that JSitemap does not generate links and supports only the links generated by Joomla.

I understand, I send the XML file generated by JSitemap to search engines independently of SH404SEF
