However, your blog does not have this JS snippet in the footer. In the same time, all your links have "hardcoded" prefixes for Alexa. I took the liberty to check your /plugins folder (http://www.bitesizebio.com/wp-content/plugins/), and it seems that you also have the original AlexaRedirect plugin installed. I think this is what's causing your problem: nevertheless Better-Alexa-Redirect is disabled, you still have the originla AlexaRedirect on: that's why all your links have hardcoded "redirect.alexa..." prefix.
For last, one advice: you seem to still run WordPress 2.2.2, while it should be better if you upgrade to the latest release WordPress 2.3.1
