Back to category button not working

[santia]

Hey everyone, i'm having this issue. Currently using joomla 2.5 and latest stable version of virtuemart

When i'm in a product detail page, the button Back to ''my store'' is not working, it doesn't links anywhere.

However, product navigation if selected on admin, works ok.

Any clues about this? i made a search but didn't find any answer in the forum.

Thanks in advance.
