1.7.0.6 Search block doesn't show any results

[thn_]

Hi

 

it's my first contact with PrestaShop and as far it's ok I can handle any problems on my own, but not this one...

 

Presta 1.7.0.6 (preinstalled by ovh on their hosting service)

Search block 1.0.5

 

I'm using Revo theme and after typing search phrase and hitting enter Presta is showing home page. I've tried changing theme to default and it was showing "no results" page. I've tried rebuilding index, setting tags for products and categories, uploading search.php from official PS package but nothing works. Strangest thing is that live search preview in ajax works fine.

Thanks in advance for any advices.
