We've resolved postmessage errors on customer sites that use iframes, and limited the use of the new iframe support to customers who request it. Unless you've asked to enabled iframe support on your Chameleon account, Chameleon won't be running the code from which errors are originating.

We've had a few customers raise concerns about errors having to do with postmessages to and from iframes on their pages. This is likely due to a recent feature release that supports iframes.
We're investigating and would appreciate any info from other Chameleon users seeing this issue.
