Could be, but it seems that you are using a old version of the theme, having all javascripts on the top. New version does not have all the scripts listed on the top, they are separated into a javascript file.
Also by my count, you have 15 extra </body></html> at the end of you theme file. Did you add those?
Try to use the most recent version of the theme and see if that helps.
[edit]: change back to default theme and check if you still have the same problem.
