Magento

Hy:

I try to install this template after install a new clean version of Magento 1.4.1
The template works fine, except to show the contents of categories.
With a Android browser show a 500 error server and wit Iphone simulator dont show any items and change the latins characters UTF-8 with a strange symbols.

If I browser direct to the item url, I can checkout correctly.

Somebody knows what happend?

Thanks
