Trouble adding WP blog to WP website

Hoping someone can help.

I am developing a WP website. It is a website in the traditional sense – it has about 40 static pages, top menu navigation, etc. These pages will remain fairly static with updates here and there, but mostly what you see is what you get.

The top menu navigation has a tab/button labeled ‘Blog’. I would like to house a WP blog on this tab. I can’t figure out how to make that work.

In Settings > Reading I have ‘Blog’ set as my posts page.

When I go into my dashboard and create a new post and attempt to publish it, it creates a page with a url of domain.com/post-name. What I need is it to post like a traditional blog where each entry would come up as domain.com/blog/post-name

I’m not sure how to do this, but as it stands it’s not working and I can’t figure it out.

If I have a static page on the site called domain.com/red-widgets-are-awesome, and try to create a blog outlining why they’re awesome, I should be able to name that blog post ‘red-widgets-are-awesome’, and have it post as domain.com/blog/red-widgets-are-awesome. As it stand, if I do that now the url will come out as domain.com/red-widgets-are-awesome. And clicking on teh blog title to read the article will resolve to the static page on my site (since the /blog part of the url will be missing)

I hope this makes sense and that there is a simple solution.

Thanks!!!
