Content controls have to be top-level controls
<p>I have a website that can be accessed from www.blahblah.com and special.blahblah.com.  The www site always works but occasionly I get a 'Content controls have to be top-level controls in a content page or a nested master page that references a master page' error on the special site.</p>

<p>It's exactly the same code running in both situations and the offending page doesn't even have a master page.  Why would it work all the time on one and fail sometimes on the other?</p>
