Not Working on New Pages

I successfully setup this plugin and created all of my pages, launched the website and everything was good.

Client tried adding a new page, and tried adding a widget to the customized sidebar using the plugin, and it does not show.

Same code, same everything as all of the other working pages.

I created a new page and the widget will not show for me either.

I have two widget areas: Primary Widget Area and Sidebar Widget Area

Primary widget area shows every time, even on new pages.

Sidebar Widget Area does not show *only* on new pages. It is working on all other pages previously setup. Does not matter what I put into the Sidebar Widget Area it will now show in my pages.

Could this be related at all to launch?
