jQuery + more won't load in header

Question

We moved jQuery to the footer using the following code:

function jquery_enque_fix() {
if( !is_admin() ) {

    // Enqueue so we can grab the built-in version
    wp_enqueue_script( 'jquery' );

    // Get jquery handle - WP 3.6 or newer changed the jQuery handle (once we're on 3.6+ we can remove this logic)
    $jquery_handle = (version_compare($wp_version, '3.6-alpha1', '>=') ) ? 'jquery-core' : 'jquery';

    // Get the WP built-in version
    $wp_jquery_ver = $GLOBALS['wp_scripts']->registered[$jquery_handle]->ver;

    // Just in case it doesn't work, add a fallback version
    $jquery_ver = ( $wp_jquery_ver == '' ) ? '1.8.3' : $wp_jquery_ver;

    // De-register built-in jquery
    wp_deregister_script('jquery');

    // Register CDN version
    wp_register_script( 'jquery', '//ajax.googleapis.com/ajax/libs/jquery/'. $jquery_ver .'/jquery.min.js' );

    // Enqueue new jquery
    wp_enqueue_script( 'jquery' );
}
}
add_action( 'wp_enqueue_scripts', 'jquery_enque_fix');

This quickly became a problem for a lot of Wordpress plugins, so now i'm trying to move it back in the header, but nothing seems to work.

Removing the above code and replacing it with:

wp_enqueue_script('jquery');

jQuery still loads in the footer section. I've tried using the code from @dipali from this thread, which should load the code in the header. Copy/Paste and still the code went into the footer..

Any ideas on what to try next?

WordPress's wp_register_script has an $in_footer parameter which allows you to state if the script should be written to wp_head or wp_footer.

By default the value is false (don't show in footer), but you could try it yourself.

Replace your wp_register_script with this:

wp_register_script( 'jquery', '//ajax.googleapis.com/ajax/libs/jquery/'. $jquery_ver .'/jquery.min.js', '', '', false );
