We made security improvements to protect your LiveSession code from being added to unauthorized sites by creating a list of trusted domains.

Using trusted domains, you can create a list of domains that you know and trust. Only those domains will be allowed to start recording. It won't work if someone tries to add your script to any website outside your trusted list.

You can set up your trusted domain in Settings -> Websites -> (chose website) -> Settings -> Trusted Domains. 

By default, the list is empty, which means every domain is allowed.
