issue with update 2.1.1. and 2.1.2

Hello,

1)
i have updated to 2.1.1 and there is a problem with price css that are changed
please check the screenshot. circled in black
on left online version without update http://www.l2gshop.com
on right 2.1.1/2 http://test3.l2gshop.com

2) is not an update issue
circled in blue is a problem for that i have asked last week and i’m waiting a reply.
I think that expose so product prices variables is truly unwatchable.
I’d like to expose only the price of the cheapest configuration with “from” before the price.
how can I fix this?

3)
now i have updated to 2.1.2 and i have a phatal error:
[17-Feb-2015 15:05:30 UTC] PHP Fatal error: Cannot redeclare woo_related_products_limit() (previously declared in /home/pwtjjwma/test3/wp-content/themes/HighendWP-child/functions.php:27) in /home/pwtjjwma/test3/wp-content/themes/HighendWP/includes/hb-woocommerce.php on line 69

I have removed from my child functions.php the code for change the related product and work
(http://docs.woothemes.com/document/change-number-of-related-products-output/)
but know i have 2 related product.

i have try to install twenty fifteen theme and include the code in the function of twenty fifteen and all work fine.
so i think that the problem is in /themes/HighendWP/includes/hb-woocommerce.php on line 69

how i can resolve?

regards

francesco
