Problems with categories

[xaxuke]

Hi from Spain!!!

The script it's great but I have a problem and I can't fix them.

The problem is with the paths of some links on the web.

I have configured seo in admin panel and add this lines to config.php:

$root_url="/";
$root_dir=$_SERVER["DOCUMENT_ROOT"]."/";

When I click on first category the link is:
http://www.elcastillodelplacer.es/catego...C3%A1ticas

When I click on other category the link is:
http://www.elcastillodelplacer.es/catego...no+HD+BSDM

The script add the categories.

When I am on a video:
http://www.elcastillodelplacer.es/video/...la+piscina

and I click on a category the link is:
http://www.elcastillodelplacer.es/video/...C3%A1ticas

The script add the categorie and the video on the same link.


When I am on a video:
http://www.elcastillodelplacer.es/video/...la+piscina

the related thumbs doesn't work because the script try to load on a page that it doesn't exists:
http://www.elcastillodelplacer.es/video/...4342_0.jpg

the img must be:
http://www.elcastillodelplacer.es/img/thumb/74342_0.jpg

Any idea?
