In the 'App Store' of your Ezoic Dashboard, you will be able to install the 'View Old Site' app. This app offers a quick way to view the old or Ezoic version of your site.

 

View Old Site

You can then select to View Old Site. This will cookie your browser so you always see your original site. You can switch back to seeing the Ezoic version by following the same steps, but selecting View Optimized Site instead.
