A script is causing my index page to auto-redirect

I created a new page this morning, and did nothing out of the ordinary. I saved the page, and immediately my site’s homepage now redirects to this URL.

• I can’t seem to do anything to fix it. I’ve tried deleting the page (creates a 404).
• I tried redirecting the page to the index (creates an infinite loop).
• I’ve sniffed through the code to see if there’s a reference of the URL, and there’s none
• I’ve looked for errant .htaccess files, and can’t seem to find any (though given the size of the site–1k+ posts and all of its associated uploads–there are quite a few directories, and as such, I’ve not ruled out this as an option

I just have no idea how to tell what’s going on…

Please, any help would be greatly appreciated.

Thanks,
Greg
