Blog template not displaying posts The blog post should display the posts created but when I got to the slug /blog it says 404 not found as well as the press news should be displayed here /press-news but same thing happens. 

If i access the posts directly : site.com/blog/blog-post-name it is displayed correctly.

an you help me giving me some probable causes so that i can check how to fix it? thanks
If you've setup a channel, it does not include a "blog index" by default, for this you need to make it yourself by placing an index.twig file within the blog folder (If that is a directory in your templates folder).

Check the answer in this question for an example on how to do the twig code.
