Hmm... One of your wordpress plugins is using obsolete code. For a temp fix, I disabled your plugins. Try enabling them one by one until you fine the one causing trouble... or, better yet, upgrade them all before re-enabling them. For my own records, the original active_plugins field in wp_options was:
a:19:{i:0;s:30:"addthis_social_widget_drop.php";i:1;s:19:"akismet/akismet.php";i:2;s:57:"askapache-password-protect/askapache-password-protect.php";i:3;s:28:"category-posts/cat-posts.php";i:4;s:32:"delicious-plus/deliciousplus.php";i:5;s:17:"flickr_widget.php";i:6;s:24:"lightbox-2/lightbox2.php";i:7;s:32:"login-lockdown/loginlockdown.php";i:8;s:30:"no-self-ping/no-self-pings.php";i:9;s:37:"secure-wordpress/secure-wordpress.php";i:10;s:55:"shockingly-simple-favicon/shockingly-simple-favicon.php";i:11;s:27:"simple-tags/simple-tags.php";i:12;s:29:"social-homes/social-homes.php";i:13;s:15:"stats/stats.php";i:14;s:59:"wordpress-automatic-upgrade/wordpress-automatic-upgrade.php";i:15;s:35:"wordpresscom-popular-posts/wppp.php";i:16;s:21:"wp-polls/wp-polls.php";i:17;s:33:"wp-security-scan/securityscan.php";i:18;s:42:"yet-another-related-posts-plugin/yarpp.php";}
With them all disabled, your blog loads though. If you narrow it down to a specific plugin that's causing the issue, and no upgrade is available (or fixing it) let me know, and we can work on it.
