moved over a site and now posts are giving a 404 error

I used snapshot pro to move over a site to a new hosting platform and all my posts events & blog posts are turning a 404 error. here is the site:

So both blog posts and event posts are turning up this 404 error though they appear fine in the dashboard. even previewing them, we're not able to view them.

Any advice? I tried to repost, but am not able to view them either. Any help is welcomed. Thank You,
