Issue
When the system property 'glide.knowman.use_live_feed' is set to true, the live feed feature is used in the knowledge article to load the comments. However, it will not load the data of the live feed and there will be the following console error.

Cause
The cause of the issue is the OOB processor 'LiveFeedAjaxProcessor'(sys_id: 149b5173471021007f47563dbb9a7114) is not active.
Resolution
By setting the processor 'LiveFeedAjaxProcessor' active, the issue will be resolved. The live feed will load in the knowledge articles' comments as well as in $live_feed.do page. However, if the customer wants to disable the live feed feature for any reason, make sure the system property 'glide.knowman.use_live_feed' is false so that the comments of the articles will not use the live feed to load.
