I'm working on a site that's kind of a blog with a shop attached, rather than the other way around. The site owner wants the index page to be the blog itself, and the shop secondary.

Right now I have Zen Cart installed in the main directory and Wordpress installed in /blog. Everything's working fine, but I can't figure out a good way of making the blog the main page. A 301 redirect on index.php makes every page on the site redirect in an infinite loop. Is there a file that's a template for the blog, that I could just copy to the index?

Any help or suggestions would be appreciated!
