Issue:

You try to visit one of the pages you've created in the OptimizePress Live Editor and you get a 404 error.

When you look at the URL, you can see that for some reason your home URL is being erroneously appended to the permalink like so:

http://www.yourwebsite.com/module-1/lesson-1 comes out as  http://www.yourwebsite.com/module-1/lesson-1/www.yourwebsite.com

Solution:

Open the Live Editor for the page(s) on which you're experiencing this issue.

Go to 'Page Settings' => Launch Funnel => and set this to OFF.

This should resolve the issue immediately.
