Hi there,
I have just purchased this theme after regretfully not doing much research and installing a theme that was too slow. I would like to switch over to this theme.
I have already built my website on the previous theme, which I believe includes custom posts.
Here are images of what the website looks like now, and also what it looks like in my WP dashboard:


When I previewed GP theme, pages other than blog and main page cannot be found.
Before I begin working on switching over, may I know how do I address this? How do I have all my posts available as per what I have now without anything missing?
Hope that my question is clear. Thank you.
