[Plugin: Ajax Event Calendar] Calendar plug in wont fully function

I am using the aspiration theme.
This calendar functionality is not fully functioning.
It show up as widgets but does not show up on the full calendar page.
I have tried the All-in-One Event Calendar as well as the Ajax Calendar.

I have found threads that say this need to before the head tag
<?php wp_head(); ?>
and this before the footer tags

<?php get_sidebar(); ?>
<?php wp_footer(); ?>

But this theme seems to be coded in such a way that i don’t think adding that will make a difference.

i also found a thread saying to modify this:
this one —

if ( !is_admin() ) {
wp_deregister_script('jquery');
wp_register_script('jquery', ("https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"), false);
wp_enqueue_script('jquery');
}

instead of this one —

if ( !function_exists(core_mods) ) {
function core_mods() {
if ( !is_admin() ) {
wp_deregister_script('jquery');
wp_register_script('jquery', ("//ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"), false);
wp_enqueue_script('jquery');
}
}
core_mods();
}

But nothing that specifically about this theme.

If anyone can tell me what to modify i am sure i can navigate down to the code and change it.
here is a link to the beta site
