[VE][html5] End of file seen and there were open elements.

Hi,

I am trying to fix the error I encounter when validating my site.  The error is a 'End of file seen and there were open elements' unfortunately I do not know what this means.

This is affecting line 601 column 21 on my site.  Specifically this string of data  <!--mfunc--

Any help to fix this would be greatly appreciated.
