Updated plug-ins in Admin, and homepage was gone

i recently updated the plug-ins(all of them) and theme went nuts. The homepage, slider and galleries are gone. Also the inner pages are showing this code:

Warning: mysql_query() [function.mysql-query]: Access denied for user ‘root’@’localhost’ (using password: NO) in /home1/jloach29/public_html/jloachdesigns.com/wp-content/themes/Orizon/gallery/includes/myPagina.php on line 256

here it’s the site address: http://www.jloachdesigns.com

Appreciate the help! I love this theme 🙂
