Problem pagination issue with J 2.5.28 and VM 2.6.18

[temerario]

I have installed J 2.5.28 and VM 2.6.18.

i have the problem with pagination when i enable the SEF.

The link is

index.php/id/category/results,13-12.html
index.php/id/category/results,25-24.html

and not with other site with VM

index.php/id/category?start=12
index.php/id/category?start=24

In this site before was installed a component for SEF but now after unistalled i have this problem.

Somebody can help me? In this moment the site is in local pc and i don't write the link.

Best regards
