    Hi there,

    I’m facing this problem on WP 3.2.1, I’m using Toolbox theme which has provided by Automatic.

    I’d like to have a widget which shows the post thumbnail before the latest post’s title. Everything is ok on testing, but it’s not on production server.

    I’ve followed the_post_thumbnail() on Codex reference page. But the error just changed to: Fatal error: Call to undefined function has_post_thumbnail()

    I have no idea to resolve, so would you please help?
    Thanks.

    Try adding these lines into your functions.php located in theme

    if ( function_exists( ‘add_theme_support’ ) ) {
    add_theme_support( ‘post-thumbnails’ );
    set_post_thumbnail_size( 140, 120 ); // default Post Thumbnail dimensions
    }

    if ( function_exists( ‘add_image_size’ ) ) {
    add_image_size( ‘category-thumb’, 300, 9999 ); //300 pixels wide (and unlimited height)
    add_image_size( ‘homepage-thumb’, 140, 120, true ); //(cropped)
    }

    after this hope your problem will be solved.
