OOPS! THAT PAGE CAN’T BE FOUND – woocommerce

Hey!

From the moment I installed the following plugin” Change Table Prefix” I got the error “oops that page can’t be found” for the pages connected to Woocommerce.

I am not sure it is correlated.In fact, when I deactivated the recently installed plugins (including the mentioned plugin), I still had the problem.

The strange thing is that when I am connected as an a administrator, the page does not have a problem. It is only when I log out.

I did the steps proposed by WPBeginners (https://www.wpbeginner.com/wp-tutorials/how-to-fix-wordpress-posts-returning-404-error/) and even others, but nothing seems to work.

What can be the problem?
