Notice: wp_enqueue_script was called incorrectly

[admin]

So I'm busy in Wordpress. I have a theme for the site and all. It's all working fine. Then I want to activate the new theme. BENG BENG, white screen of death. I debugged and this is the error:

Notice: wp_enqueue_script was called incorrectly. Scripts and styles should not be registered or enqueued until the wp_enqueue_scripts, admin_enqueue_scripts, or init hooks. Please see Debugging in WordPress for more information. (This message was added in version 3.3.) in C:\xampp\htdocs\wp-includes\functions.php on line 2944

Line 2944 is just the line that throws an error. I already checked that.

Anyone ever experienced and solved this?

EDIT:

Referencing lines:

    function _doing_it_wrong( $function, $message, $version ) {

    do_action( 'doing_it_wrong_run', $function, $message, $version );

    // Allow plugin to filter the output error trigger
    if ( WP_DEBUG && apply_filters( 'doing_it_wrong_trigger_error', true ) ) {
        $version = is_null( $version ) ? '' : sprintf( __( '(This message was added in version %s.)' ), $version );
        $message .= ' ' . __( 'Please see <a href="http://codex.wordpress.org/Debugging_in_WordPress">Debugging in WordPress</a> for more information.' );
        trigger_error( sprintf( __( '%1$s was called <strong>incorrectly</strong>. %2$s %3$s' ), $function, $message, $version ) );
    }
