 * I noticed the following javascript error related to dataTables:
 * URL: /wp-admin/tools.php?page=acui&tab=homepage
    ERROR: TypeError: Cannot read
   property ‘mData’ of undefined 1 File [https://cdn.datatables.net/1.10.24/js/jquery.dataTables.min.js](https://cdn.datatables.net/1.10.24/js/jquery.dataTables.min.js)
   line 107 col 298 in HTMLTableCellElement.<anonymous>
 * It did not seem to have any adverse consequence but thought I would still report
   it.

 * When do you get this error?

 * I do not have a precise answer to that question. I am using rollbar to detect
   and report JS/PHP errors and warnings.
 * I was importing some users. The only warning I remember seeing on the backend
   was when I tried to import an existing user with matching email address but a
   different username. I ended up canceling that import because it was a typo on
   my part.

 * This warning is created by DataTable.
 * If there is something strange in the table, it can be rendered, but maybe it 
   throws some errors in console.
 * If the table is showing correctly, you have no problem in importing and I cannot
   reproduce it I cannot solve it.
