Single Post Page not displaying

[rrdesignweb]

Hi, great theme.

I am able to display the list of posts from another wordpress site custom api however It will not display the single post page upon clicking the post title.

I get "Object Not Found!" on page refresh.

Have set on posts, post, page src files.

Permalink structure is fine, set to and shows post name slug not sure what the issue could be?

Thanks
