Hi there,

You have to enable this options 'Login To Read Full Post' at Backend>Components>EasyBlog>Settings>General in order for guest to be able to view your blog's post as shown https://screencast.com/t/tcA060PgsKm. Please give it a check and see how it goes

I the problem still persist, can your provide us with your backend and FTP access for further check on this issues? Please advice
