ultimate urls problem

[ras]

Hi

i use the ultimate seo urls every thing is working fine exept when i click on products from the wats new box i some times get "Product not found!" and the url is not complete

 

if it normaly looks like this :

 

http://domain.com/product-p-5920.html

 

the incomplete url is :

 

http://domain.com/-p-5920.html

 

i dont know if its the ultimate seo url or its my database.
