wordpress 3.5 update error

I updated my site (beyondlimitsmagazine.com) to wordpress 3.5 today and I got the following error(s):

Warning: Missing argument 2 for wpdb::prepare(), called in /nfs/c04/h01/mnt/66714/domains/beyondlimitsmagazine.com/html/wp-content/plugins/sharebar/sharebar.php on line 112 and defined in /nfs/c04/h01/mnt/66714/domains/beyondlimitsmagazine.com/html/wp-includes/wp-db.php on line 990

Warning: Missing argument 2 for wpdb::prepare(), called in /nfs/c04/h01/mnt/66714/domains/beyondlimitsmagazine.com/html/wp-content/plugins/sharebar/sharebar.php on line 124 and defined in /nfs/c04/h01/mnt/66714/domains/beyondlimitsmagazine.com/html/wp-includes/wp-db.php on line 990

reinstalling the update didn’t fix it either. any help would be appreciated
