I'll explain the basic gist of how the new Page Rules work.
Page Rule Manager you can specify which pages will trigger the Page Rule.
You can then tell Buttonizer if you want to hide or show the button when the Page Rule gets triggered ( When the user arrives on the page you specified )
That was the basic gist of how Page Rules work.
Jeroen was then saying that you can exclude the button on a specific page by selecting "Hide button when rule is triggered" ( see photo #2 in the explanation ).
I hope this explains on how the new Page Rules works! 😁
