When using conference, the JavaScript console returns a Internal Server (500) error, and neither the main conference application or the persistent chat window automatically update. Refreshing the page does display the updated threads.

The redacted PHID-USER is for a chat user that left the chat thread using the cross/delete icon from participants column in the main conference application.
Within the conference application the participants column only shows the two remaining (active) participants in the thread, however when clicking on the 'messages' icon in the site header, the resulting dropdown menu listing the threads and participants, still displays the username for the user that left the thread.
