[Plugin: In Over Your Archives] Weird error for non-current months

Just set up IOYA on my site and I love the way it looks when I first load up the page to the current month of archives.

The problem happens when I click to prior months… instead of pulling up a page of thumbnails and post excerpts, it brings up the whole home page (complete with the front page side bar and all the front page widgets) within the content portion of the archive page. I’m not quite sure what to do about this or even where to begin pinpointing what may have gone wrong.

Any help or suggestions are most welcome, but really, until there’s a way to solve this issue, I can’t really use this plugin (which makes me super duper sad because when it works right, it looks AWESOME).
