Update pie.htc in /css folder. Just google to find download.

Hi Milos,

I've updated the file in the template folder, but it didnt solve the problem.

Try this, open index.php of template and find this line:


<!--[if lt IE 9]>

change it to:


<!--[if lte IE 9]>

Thanx man, this fixed the problem!
