Sorry for My English

my theme use products i wish it could be included in this plugin however it is everywhere not on my products of the theme to exclude them

In the past install the module but i uninstall

Now I have reinstalled it, and it puts the pages that I had previously configured as hidden, I do not want it to do it, I want to have it reset (I do not want to edit article to article)

?Solutions?
