<p>The MathJax CDN was being updated from version 1.1a to version 2.0 yesterday and there was a glitch that prevented the old version from expiring properly, so there was a period of time when people were getting some files from version 1.1a and some from version 2.0, causing the math processing errors that you saw. If you were lucky, you got enough v2.0 files to process the page.</p>

<p>The issue was fully resolved about 8 hours ago (2:30AM EST), so if you are seeing further issues, try clearing your browser cache and reload the page. Some browsers may also need to be restarted to completely clear the cache.</p>
