this was the exact problem i had when i installed the avatar hack, unfornuently i just got rid of the code as it was too much hassle, im not quite sure how to fix it, but i would suggest you email/PM the guy who actully made the hack and show him the screenshot, or give him your URL.
i wish i could help, but seen as i didn't fiqure out the problem when i attempted to install it myself i can't
