• Woocommerce price filter ordering by Post ID rather than price high to low

  I'm stumped at this one.

  I've got Woocommerce and using the theme 2017 (All other plugins and themes disabled) and I'm looking to order them in price High to low however when I select this dropdown and press it the prices are not being ordered instead it's being ordered by Post ID instead.

  

  All the prices are correct inside of the database also

  
• Allow to remove product automatically added from cart in Woocommerce

  In Woocommerce, I am using this official code snippet to automatically add a to cart a product when customer visit my website:

  add_action( 'template_redirect', 'add_product_to_cart' );
  function add_product_to_cart() {
      if ( ! is_admin() ) {
          $product_id = 1234; //replace with your own product id
          $found = false;
          //check if product already in cart
          if ( sizeof( WC()->cart->get_cart() ) > 0 ) {
              foreach ( WC()->cart->get_cart() as $cart_item_key => $values ) {
                  $_product = $values['data'];
                  if ( $_product->get_id() == $product_id )
                      $found = true;
              }
              // if product not found, add it
              if ( ! $found )
                  WC()->cart->add_to_cart( $product_id );
          } else {
              // if no products in cart, add it
              WC()->cart->add_to_cart( $product_id );
          }
      }
  }
  

  It works fine and adds the product to cart.

  But I want the customers to provide the option to remove this item from cart if they don't want it. But actually the product cannot be removed.

  How can I make the product auto added to cart removable?
• Silverstripe Install - Friendly URL's Not working

  I have tried to install silverstripe 4.2.1 on two different servers and am getting the same error on install.. I have multiple installations this year on other client machines but this is the first time I have run into this problem. Wondering if it is a 4.2.1 problem

  The error message on installation

  Friendly URLs are not working. This is most likely because a rewrite module isn't configured correctly on your site. You may need to get your web host or server administrator to do this for you:

  mod_rewrite or other rewrite module is enabled on your web server
  AllowOverride All is set for the directory where SilverStripe is installed

  I have placed some garbage text in .htaccess at root, in public_html and in the silverstripe public folder. All three cause a 500 error.

  Note that i was able to visit site.com and it redirected to the installer. so I would think that mod_rewrite is indeed enabled.

  When I visit site.com it gives the silverstripe version of "Server Error"

  My HTAccess file located in the public folder of SS:

      ### SILVERSTRIPE START ###

  I need help to understand the documentation for Fluent, from here Fluent config documentation

  The documentation says: "You can create locales via the /admin/locales CMS section."

  When I create a locale, for example english, and then click on it I get at popup saying "Not Found". Do I need to install the locale somewhere else before using it?
