When I set up an external link in sitemap on my main nav it does not work. I tell it to link tohttp://www.mysite.org/prestashop but it links towww.www.mysite.org/concrete5/index.php/prestashop... which remains in the concrete5 cms instead of linking externally to my prestashop site.
FYI: they are both stored on the same server but in different directories, ie. concrete5 cms is stored in concrete5 dir and prestashop cms is stored in prestashop dir.
I also have a wordpress cms dir that I also want to link to from the concrete5 cms site.
