Hello Mariela,

Nice to see a pretty face here for a change.

Please check www.sakic.net/support/faq/sef_advance/#2
Does your built-in SEF work? Which .htaccess file do you have? It could be mod_rewrite that doesn't work correctly on your server.

By built-in SEF I mean SEF that comes with Joomla, when SEF Advance is uninstalled or deactivated. You activate it in global configurations.

Ohh Yes the SEO is on at the joomla backend.
Please try to help us , we need finish that project

OK but uninstall SEF Advance and turn on SEO in global configuration.
Then see if the built-in SEF URLs work.
