Cannot read property 'whiteListIframe' of undefined


I am getting this error “Cannot read property ‘whiteListIframe’ of undefined”. I am loading a iframe into my Discourse. Because of this error the javascript function of the website which is loaded in iframe is not working.

Is there any way through which i can resolve the whitelist frame error in my current discourse version or do i need to upgrade the version.

Please help me resolve this error.

Easiest way to solve this is to update to latest version of Discourse.


Also looks like this is coming from a 3rd party plugin, it is possible you have a plugin that no longer works on Discourse.
