hello,
I created a site with ads joomla 1.5, and to optimize its www.laboursedu2roues.fr I use Artio JoomSEF SEO and the specific extension jdirectory for url rewriting.
On the site the main menu is arranged on top. The problem is that when I click on the title of a property, such as the ad title "test" in the "Moto Scooter Quad" (Motorcycle Scooter Quad) page, the highlight of the current page back on the menu "Accueil" (Home).

However if I disable all 3 options SEO since the general configuration of the admin panel:
- Explicit URLs (SEF)
- Apachemod_rewrite
- URL Suffix

I do not have this problem and the highlight remains on the page.

I did everything but I can not find how to find a solution to this.

Thank you in advance for your quick help.
