So a site I helped develop utilizing WP was working perfectly for about two months. Seemingly on it's own, one of the links in the menubar stopped working.
If you visit http://www.bdingredients.com and click the 'News & Events' link in the menu bar you'll see that it displays the home page again. It should be taking you to a different page (the blog section of the site, actually) but doesn't any longer. The template for the page is in place, the menubar link is a page and not a post so the permalink shouldn't be an issue (or is it?) and what's most frustrating is that it was working before, even though the url in my browser address bar does reflect the correct page.
This happened seemingly on its own. I see no blog posts or edited pages since I touched the site. I feel like I'm missing something obvious but don't know what. I did backup everything and update everything and still it's a problem.
