Post page not working correctly

I have been using a subdomain blog.vexguardpestcontrol.com for my blog because the theme I use to run on the gantry network would not allow the blog page to be in the main site. I have switched to a new theme and deleted the subdomain, imported my posts from the subdomain. I set a static page and the blog page. When I try to goto the blog page it shows up weird and without any of the posts on it.

the website is https://vexguardpestcontrol.com the blog is vexguardpestcontrol.com/blog

Thanks.
