Problem with Product Neighbours (previous-page, next-page)

[Piombo]

Hello!

VM ver. 2.0.26
Joomla ver. 2.5.17

Suddenly, i have a problem with Product Neighbours on product page.

I have 4 items - A B C

When i go into the first item "A" - i see previous-page (<- to B) next-page (-> to B)
When i go into the item "B" - i see previous-page (<- to A) next-page (-> to A)
When i go into the last item "C" - i see previous-page (<- to A) next-page (-> to A)


Probably, the problem happened after the changed names created product without changing the alias.
- But later I recreates aliases in all items in categorie
- I delete all VM cashe "/cache/com_virtuemart_cats/*.*"
- I switched on and off in the settings navigation
- I did not touch the code in the /components/com_virtuemart/views/productdetails/tmpl/default.php

Problem stay! Please help!

I found a solution, but an older version (http://forum.virtuemart.net/index.php?topic=96784.msg408999#msg408999)
