Viart Shop

I just installed this version and I found two problems:
 
1st: The opinion poll title and its options are not centred properly.
 
2nd: the buttons are gone. I mean "read more" and menu buttons.
 
Just have a look to my site in order to see what i say www.arenadejuegos.com
 
Probably I screw something when doing the upgrade Does any one have a clue??
