Pro Sites - Page Quota doesn't work - critical bug for me :(

Hello,

Page Quote doesn't work for me. I have set the limit to 1 page for basic plan, but the user can still create more pages. It's a critical bug for me, as my first plan shouldn't allow to create more pages. Could you please check that out. I can remember it was working in some previous release of Pro Sites. I will test it also on clean installation and let you know.

I have granted access to the website.

Best regards,
Damian
