Hi,
thanks for that information! This means that there’s something wrong with the loading of the jQuery JavaScript library. Something on your site (a plugin or the theme) is loading an old version of jQuery. This can for example happen when jQuery is loaded from a CDN (like the Google CDN).
Please check the “View source” function in the browser, and search for “jquery”, to find out where it’s loaded from.
If that does not help, I recommend to temporarily turn off all plugins (except TablePress) and switch to the WordPress default theme TwentyThirteen. Then, re-activate the plugins one by one, until the problem happens again. You have then found the responsible plugin (or your theme).
Regards,
Tobias
