I have been using WordPress SEO by Yoast for sometime. Suddenly, the home page title is not showing anymore. Instead, it is showing the site name | Home. Everything is filled in correctly. All other pages are showing the correct titles. This is happening on 2 sites of ours that have the 3.4.1 version. On another that is 3.4.1 it is still working correctly. On sites that are still 3.4, the home titles are still showing correctly. Not sure what to do at this point.
