On 1-Jan-2011, I had installed JoomSEF on two different websites, and it worked 100% with no problem.

But, on 13-Jan-2011, I installed JoomSEF on a third website. It does successfully transform the normal links to SEF links. However, when I click on the SEF link, I get a page which says "404 Not Found".

I have looked at all of the settings on this failing website, and compared it to the previous two, and it is absolutely identical. So, I am confused what I am doing wrong.

It is a very simple 4-page website:

www.laforcephysique.com
www.laforcephysique.com/services
www.laforcephysique.com/about
www.laforcephysique.com/contact
www.laforcephysique.com/blog

Hello,

If the SEF links are created normally but they throw a 404 error, it means there some problem with URL rewriting on the server. Is the server Apache or IIS? For Apache, check if the .htaccess file is configured properly and that it is allowed on the web server. For IIS make sure that the Rewrite module is configured correctly.
