worpress44 on "[Plugin: WooCommerce] Nothing Found Error in My Account Page"

Woocommerce 2.5.5 with storefront.

I get "Nothing found" error when I access MyAccount.
If I append mysite.com/my-account/edit-account ,
then it takes me to Shop Page.

I saved Permalinks again as default.
Any help ?
Thanks
