When loading a chat within the agent console the transcript is showing as plain text, and the agent is unable to scroll.
Oracle Service Cloud, Chat, All supported versions
When a chat is first loaded into the Oracle Service Cloud agent console a request is made to Oracle's servers for a .css (cascading style sheet) file that describes the look and formatting of the chat transcript window.
This request looks as follows:
If this file cannot be accessed by the client the chat transcript will be devoid of formatting, and you will be unable to scroll through new responses if they exceed the chat window length.
This image displays the chat transcript without formatting (a 'bad' result):
This image displays the chat transcript with formatting (a 'good' result):
The most common cause for this issue is a proxy server or web filter that is actively blocking the 'agent.css' request. If all other functionality within the chat window is working properly please consult with your internal IT team to make sure access to this resource is allowed.
