Blog home is missing (404) all links to posts, categories, and tags are fine

I’ve read countless posts on similar issues here but have not found anything that exactly addresses my issue. I’m going to define the problem and propose a solution which I’m not sure about. Your thoughts will be greatly appreciated.

The Problem: My blog homepage is missing. All other posts, category, and tag links are fine.
Blog home: webartisan.biz/resources/
Example post link: http://webartisan.biz/start-coding-with-wireframes-and-pattern-libraries/
Example Category link: http://webartisan.biz/category/resources/web-writing/

Everything was fine through mid or late February which was the last I checked the blog homepage. The only thing that has changed on the website are the WordPress automatic updates. The webhost ran a file history check and no other files were hacked or otherwise updated. Plugins had not been updated so I updated those but that had no effect.

Proposed solution: I think there’s a chance the following idea may work but I don’t want to break the entire site in the process so let me know what you think. My thought is to create a new page, make sure it appears, then designate that as the posts (home)page under settings > reading. My fear is that it may break all of my permalinks. Or, it might work.

Thank you in advance for your thoughts.
