Problem with baseurl and interaction with plugin

Most of the problem was resolved by pasting the following into my functions.php

     function my_init()   
{  
    if (!is_admin())   
    {  
        wp_deregister_script('jquery');  

        // Load the copy of jQuery that comes with WordPress  
        // The last parameter set to TRUE states that it should be loaded  
        // in the footer.  
        wp_register_script('jquery', '/wp-includes/js/jquery/jquery.js', FALSE, '1.11.4', TRUE);  

        wp_enqueue_script('jquery');  
    }  
}  
add_action('init', 'my_init');
