title: Datatables: Uncaught TypeError: Cannot read property 'parentNode' of undefined
body: <p>I'm getting two errors in my console upon viewing a webpage. Datatables is being used, and I am quite sure (as the errors state) that the issue is related to Datatables. The problem here is that I did not write this code, I am merely now trying to fix issues in the code. The odd thing is that this section of the code should have been working before, as I can visibly see it working on the live version. Am I correct in what I believe to be the error? If so, what is the best way to go about debugging this, when the code is not made by me, and the code and data is in large quantities? </p>
