Warning: Call-time pass-by-reference deprecated

I just purchased TableJX, downloaded it and installed it. It is very easy to use. But, I received the errors below the first time I tried to display it in a content article. Can you help?

Warning: Call-time pass-by-reference has been deprecated in /home/content/f/8/5/f85jetfire/html/plugins/content/displaygrid.php on line 100

Thanks! That fixed my problem. I no longer receive the error message.
