We have recently purchased a module to extend woocommerce.  The module allows the customer to choose their currency.  This is the module - http://aelia.co/shop/currency-switcher-woocommerce/

When I activate the module, I get fatal errors:

Catchable fatal error: Argument 1 passed to WC_Aelia_CurrencyPrices_Manager::convert_product_prices() must be an instance of WC_Product, null given, called in /home/gabbys/public_html/wp-content/plugins/woocommerce-aelia-currencyswitcher/woocommerce-aelia-currencyswitcher.php on line 400 and defined in /home/gabbys/public_html/wp-content/plugins/woocommerce-aelia-currencyswitcher/lib/classes/multiprice/wc-aelia-currencyprices-manager.php on line 467

I tried disabling the theme and activating Twenty Fourteen and there are no problems with that theme, which leads me to believe the issue is with Shoppica.  What should I do to try and get this plugin to function with your theme?

Thank you!
