content of pages not showing up

Hi,

I have my site on https://bodysuits4babies.com/ but this is with a different nameserver on the domain. I am trying to change the nameserver to ours. So what i did is took a backup of the site & installed the same site at https://yoursitez.com/new/ so that once i have it running on one of my servers, i can change the nameserver to mine & then replace the blog.

Now the main post page is working allright but the inner pages like
ABOUT US, ADVERTISE HERE, AFFILIATE DISCLOSURE & PRIVACY POLICY, CONTACT US, REVIEWS are not showing any content. It goes to a page which says

“This is somewhat embarrassing, isn’t it? It seems we can’t find what you’re looking for. Perhaps searching can help.”

Having said that in the dashboard, all the content & media for the inner pages is showing up in the admin.

What is my programmer doing wrong? She has been at it for a week but no luck.

Thank you for your help.

Regards,

Kapil
