Issue with guests

Hello.

So I have installed Woocommerce. I’ll continue on with my problem:

I’ve installed a plugin that hides the prices and the “add to cart” buttons from all the products on my site. I’ve selected two options that hides what I said above from both the logged-on users and the non logged-on users. Everything is well when I am logged in, I don’t see any prices nor “add to cart” buttons. But the problem rises up when I’m not logged in. Somehow, the prices are still shown, and the buttons too! It feels just like the guests are not recognized… ?!… or something like that. I’ve spent the past 2-3 hours looking for a fix but there’s none on the internet.

I’m not really sure if this is the right place to discuss this problem, but I’m pretty desperate about getting it fixed.

Thank you so much.
