Superslides for Mobile

To make the superslide script work also for mobile in addition to the left & right arrow key add this snippet:

$("#slideshow").on("touchstart", function(event){
        var xClick = event.originalEvent.touches[0].pageX;
    $(this).one("touchmove", function(event){
        var xMove = event.originalEvent.touches[0].pageX;
        if( Math.floor(xClick - xMove) > 5 ){
            $(this).superslides('animate', 'next');
        }
        else if( Math.floor(xClick - xMove) < -5 ){
            $(this).superslides('animate', 'prev');
        }
    });
    $("#slideshow").on("touchend", function(){
            $(this).off("touchmove");
    });
});

Setting permissions for wordpress

Everyone experiencing this issue should execute these commands:

sudo usermod -aG www-data $USER

Adds the currently logged in user to the www-data group.

sudo chown -R www-data:www-data /var/www

Changes the ownership of the /var/www directory to www-data group.

sudo chmod -R 755 /var/www

If this doesn’t fix the issue you’re having, you’ve got something else wrong and bashing DO is not going to help anyone. If you want a managed server, look for hosting elsewhere. If you need help, ask someone or hire an admin that knows how to not only ‘set things up’ but knows how to secure your server as well. You’ll be glad you did. DO is not for novices, even if they have a lot of tutorials.

Include Bootstrap Styles and Scripts In A WordPress Theme From CDN

If you are using WordPress then it’s not a good idea to directly link your stylesheet and JavaScript in the header.php (or footer.php) file. Instead WordPress includes enqueue functions to add them to your theme which is the proper way to add jQuery and other scripts.

The following 2 functions should be added to your functions.php file to include the required files. It adds the Bootstrap stylesheet & the default theme stylesheet (uncomment the ‘my-style’ line in the pwwp_enqueue_my_scripts() function to enqueue default stylesheet) in the head and the Bootstrap JavaScript & jQuery in the footer. It also tells WordPress that the Bootstrap JavaScript file depends on jQuery being loaded for it to function.

function tc_enqueue_my_scripts() {
    // jQuery is stated as a dependancy of bootstrap-js - it will be loaded by WordPress before the BS scripts 
    wp_enqueue_script( 'bootstrap-js', '//maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js', array('jquery'), true); // all the bootstrap javascript goodness
}
add_action('wp_enqueue_scripts', 'tc_enqueue_my_scripts');

function tc_enqueue_my_styles() {
    wp_enqueue_style( 'bootstrap', '//maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css' );

    // this will add the stylesheet from it's default theme location if your theme doesn't already
    //wp_enqueue_style( 'my-style', get_template_directory_uri() . '/style.css');
}
add_action('wp_enqueue_scripts', 'tc_enqueue_my_styles');
