Sidebar is nothing but SQL errors

I had been using a template that did not use any of the normal WordPress sidebar features and manually set all links, so I never knew about this until today. Recently, my page ended up getting automatically blocked in China (somehow due to my template) and changing my template fixed the problem. However, every template I try, even the WordPress default, shows endless SQL errors for every sidebar field save “search.”

The strange part about this is, the rest of the site works perfectly. All the links open fine, things show what they are supposed to, and the only other error is an ob_start message at the top courtesy of my server’s PHP running on paranoia settings.

You can check the page yourself at http://www.cinnamonpirate.com/. It seems to me that somehow $wpdb does not even exist despite it being pulled into the sidebar functions with a global command. If you look at the exact SQL error, it dies because things it depends on from $wpdb are not present for the query.

I already wiped out my original files and replaced them with the WordPress 1.5.2 release on this site, just in case one of my changes was responsible.

The errors are:
