Back next page do not work

[androclo]

the site is in catalog mode and joomla is version 2.5,
virtuemart version is 2.0.14

if I try to go next or back with the pages does not work, the page looks like and update back to the same page,

at the time i solved the problem by simply entering 50 products per page,
as you can guess if i put more products, for example, 200, becomes too long to see,

is there any solution?
