recently published post became the homepage

my website is http://www.brackers.com I created this site with wordpress about 4 years ago or so, and am a savvy wordpress user, but i have minimal coding skills. The site is set to have a dynamic homepage, utilizing (at this time) one of the “Elegant Themes” (specifically, Trim), which I have customized (Previously I have used other themes. I have had this one in place for about 6 months). A little over a week ago, I published a post (post name brackerskc) announcing a new location for our store. Upon publishing, that post “took over” the home page. if you click on the link to my main site (or type it in directly), it automatically redirects to brackers.com/brackerskc. Same thing occurs if you click the logo on the top, which should take a person back to the home page. I disabled all the plugins and the site returned to the regular home page for about 30 minutes, then reverted back to the post, so I don’t think the problem is a plugin. I switched the them to 2012 or 2013 (one of the standard built-in themes), and that did not solve the problem either, so I’ve ruled out the theme. I’m positively perplexed, and any help would be hugely appreciated.
