Blog Metro Problem

Hello!

I need your help to config UNCODE theme on my site.
All the server system status are OK. The demo content was imported fine.

But the problem is: some pages load, some don't.
All Wordpress configuration was made.
I try to disable plugins, increase the limits, but the problem stil there.

I need to use BLOG METRO as homepage, but that page doesn't open.
I don't understand why some pages are working, and some pages don't.

Please, check this to me.
I already sent Wordpress and FTP details to your email.

The site is http://fruteirafrutano.com.br

Thanks!
