Hey Rasimakis, I will be updating this version to 4.7 compatible soon. Thanks for your valuable suggestion.
Hi, @girlieworks. i have deleted shop page even from trash and there is no other page with same name. I tried everything from my side. But i think that is may be the woocommerce shop page but i am not at all using that page anywhere in my website.
As pointed out , its not a caching problem if it is then let me know how to solve by your knowledge .
thanks @stanordan @sterndata , this url (http://www.mypage.com/shop/) is a dummy url. Likewise i deleted my shop page but then also it is accessible through above given url pattern. I tried from different systems also. I restricted my other page for registered users only based on user role using wp-members and user-role editor.
