Don't know what responsive tables have to do with the iframe.  You can simply test the pro feature then maybe on a different page or in a different installation.

Or simply buy it :).

The tables are around the iframe right? 

the iframes are working great now, thank you! but the weird thing is that on mobile they blink and refresh with any touch and sometime without touching, do you know what can be the problem? I already have the SSL configuration and the https works perfectly on pc but on mobile this happens, they blink and refresh, any idea?

How does you full configuration now look like? Because right now I don't see anything you do inside the iframe. So the refresh/blink is something which happens inside the iframe my plugin cannot influence.

What you can maybe do is to configure the iframe that is is only displayed when it is fully loaded and display a loading indicator at this time.

Best regards,
