Problems with version 2.2.2

Hello,

I just downloaded the version 2.2.2 at the ALX Media website, but for some reason when download and activate the theme, as soon as I preview my website I get a couple of error messages at the top of my page.

What did I do wrong, I trying deactivating and installing again a couple times, but the error persists.

HELP!!

These are the error message I get:
