Search module problem

[NoSGR]

Hello to all there!

I've installed latest version of virtuemart & joomla on my website.

But after i added the Greek Language pack, Virtuemart Search Module stopped working and i don't know why! Products in categories are displayed correctly but search won't work. I just get an empty page.

My website's Link: http://www.helloheaven.gr

Can you please help me to fix the problem?

Thanks in advance!

Any suggestions?
