I'm having a weird issue while setting up a site. It almost seems as though the /blog/ url is reserved or already in use, only it isn't as far as I can tell.
I setup a new page called 'Blog' and set the permalink to '/blog/'. Then under 'Settings' => 'Reading' I set the Posts page to be 'Blog'. Then I went one step further and setup a new template called 'tpl-blog.php' and assigned it to the 'Blog' page.
After all that I entered some content in and it and tested and it didn't look right, none of my text was in there and a lowercase 'blog' was showing up for the title. I tested a bit more and found it was using the page.php file instead of my custom tpl-blog.php.
Thanks for any help!
