When creating post-chat surveys, if the default question "Would you like us to email you a transcript of this chat?" is modified to have more than two radio-button responses, it will result in the following error:
Unable to save 'Post-chat survey' for one of the following reasons:
1. Server error
2. The HTML code in your survey contains unsupported elements and/or attributes.
This is because the default question has been designed to have just two radio-button responses.
If you would like to have more than two responses, then you must create a new question. The default question can be deleted if required.
Note: This article and issue only applies to our legacy Live Chat platform. If you are still using our legacy platform we encourage you to consider transitioning to our modern Messaging platform.
