error: invalid agrument

You probably have no custom menus configured (Appearence > Menus), which this plugin requires in order to work. The error message could be a little more informative though, so I will see if I can push a fix for this shortly. Meanwhile, could you confirm that creating a custom menu fixes the issue for you?

yes this issue is fixed.

however i’d like to seek some help from you. i am new to woocommerce and have added products to it. now in order to assure the changes are made to the website can you please tell me what to do next. also, let me know how to activate the add to cart button.

Hi Prateek,
The add to cart button should work out of the box.
If you want your products to appear on the website, make sure you have added the shop page to your custom menu (if you are using permalinks, it should be something like yoursite.com/shop). When the cart is empty, WooCommerce Menu Cart will also link to this page. WIthout a link to your website, it’s hard to give you any precise directions.

I suggest searching for a WooCommerce tutorial online (here’s one: Getting started with WooCommerce). Also, make sure your theme supports WooCommerce. Let us know if you have any issues with the WooCommerce Menu Cart though!

Kind regards,
Ewout

will surely start with some online tutorial.
Thanks Ewout
