PHP Error on cart page

Everytime the cart page is loaded I get this error for each up-sell.

PHP Warning:  include(/~/shop.matthewsparkes.co.uk/wp-content/plugins/wc-j-upsellator//templates//modal/triggerable_gift.php): Failed to open stream: No such file or directory in /~/shop.matthewsparkes.co.uk/wp-content/plugins/wc-j-upsellator/helpers/Helpers.php on line 238

I have looked in the file structure for the plugin and I can’t find the file at all?

Even though the url seems to be broken with double // the triggerable_gift.php file does not exists (~or//templates//mod~)

If I edit your plugin and remove the double // it still can’t find the file? See below…

The page I need help with: [log in to see the link]
