Support » Fixing WordPress » Slider – Theme conflict with old Jquery Version

  • vince23


    Hey, Im using an outdated theme (showcase) and the Revolution slider.

    I m having trouble gettin the slider to work as produces the follwing error message :

    The Current Version of jQuery:1,4,2
    Please update your jQuery Version to min. 1.7 in Case you wish to use the Revolution Slider Plugin

    I ve tried to replace the old js-files in the theme folder but it didn’t help.

    here are the linked jd-files in the fuctions.php:

    wp_enqueue_style( 'showcase', get_bloginfo( 'stylesheet_url' ) );
      wp_enqueue_style( 'font-titillium', get_template_directory_uri() . '/fonts/titillium/stylesheet.css' );
      wp_enqueue_style( 'font-leaguegothic', get_template_directory_uri() . '/fonts/leaguegothic/stylesheet.css' );
      sc_enqueue_style( 'ie6', get_template_directory_uri() . '/ie6.css', 'IE 6' );
      sc_enqueue_style( 'ie7', get_template_directory_uri() . '/ie7.css', 'lt IE 8' );
      wp_enqueue_script( 'jquery', get_template_directory_uri() . "/js/jquery-1.4.4.min.js", null, '1.4.4', false );
      wp_enqueue_script( 'md5', get_template_directory_uri() . "/js/md5.js", null, null, false );
      wp_enqueue_script( 'prettyjs', get_template_directory_uri() . "/js/pretty.js", null, null, false );
      wp_enqueue_script( '', "", array('jquery'), null, false );
      wp_enqueue_script( 'showcase_scripts', get_template_directory_uri() . "/js/scripts.js", array('jquery', ''), null, true );
      if ( $is_IE ) {
       wp_enqueue_script( 'DD_belatedPNG', get_template_directory_uri() . "/js/DD_belatedPNG.js", false, null, false );

    What I did is: I replaced the “jquery-1.4.4.min.js” with a modern version (1.9 or 2.0). What am I doing wrong ?

    Could you guys help me out ?

  • WordPress core automatically loads jQuery v1.8.3, but for some reason it looks like your theme is loading an older version instead.

    You can try commenting out this line:

    wp_enqueue_script( 'jquery', get_template_directory_uri() . "/js/jquery-1.4.4.min.js", null, '1.4.4', false );

    …by adding two forward slashes before it, like this:

    // wp_enqueue_script( 'jquery', get_template_directory_uri() . "/js/jquery-1.4.4.min.js", null, '1.4.4', false );

    That should prevent your theme from loading its version of jQuery, allowing WP core to load its version instead.



    Thanks for the answer but that didnt work.

    Well, the issue is clearly that your theme and/or some other plugin is loading an outdated version of jQuery. One way to resolve the issue would be to add this to your functions.php file:

    function jquery_reset_06232013() {
        wp_deregister_script( 'jquery' );
            $handle    = 'jquery',
            $src       = '//',
            $deps      = array(),
            $ver       = '1.8.3',
            $in_footer = true
        wp_enqueue_script( $handle );
    add_action( 'init', 'jquery_reset_06232013', 999 );

    This should fire after anything else that is registering the script; de-register it; and then register it using a version from Google’s CDN.

    If that works, that means something besides your theme is registering the wrong version of jQuery and should be hunted down and destroyed. 🙂



    sorry but that didnt work aswell.

    I really dont know what is causing the problem.

    The only plugin I have is qtranslate which doesnt use jquery at all.

    So it must be the theme (which is from 2011 I think).



    Does it make a difference if I work locally (with bitnami)

    or online ?

    @vince23, hope you solved it already.

    Make sure that if you’ve created a child theme that the parent isn’t calling an older version. If it’s twentyeleven, it might be related to the call in showcase.php:

    wp_enqueue_script( 'twentyeleven-showcase', get_template_directory_uri() . '/js/showcase.js', array( 'jquery' ), '2011-04-28' );


    I am having the same problem with my site and cannot figure out what is stopping wordpress from reading the the new jqery update.

    @vince23 did you solve the problem? how?
