Today i ran into this warning when testing IE7 compatibility for a web project:

Message: HTML Parsing Error: Unable to modify the parent container element before the child element is closed (KB927917)

The problem is that the site has some JavaScript code that tries to modify the parent of a DOM-node from the a child node before the child is finished loading. Here's a short example of a how to get the error:
<br /> <div id="parent"><div id="child">Same ol' child<br /> <script> document.getElementById('parent').innerHTML = 'New child'; </script><br /> </div></div>
The content will still be replaced but with a warning in the console. To get rid of the warning just move the script out to the parent container, ie.
<br /> <div id="parent"><div id="child">Same ol' child<br /> </div><script> document.getElementById('parent').innerHTML = 'New child'; </script><br /> </div>
OR, even better, use body.onload or jQuery(document).ready.
If you want more information about this problem head over to Microsoft's support site:
