Symptom
Visitors using IE11 experience very slow co-browse, or the co-browse session disconnects when a visitor navigates to another page.
This has been seen on websites hosted on Weebly, though other sites may be affected.
The IE Console may contain the following error Message:
SCRIPT5007: Unable to get property 'appendChild' of undefined or null reference assist-bootstrap.js (64,9)
Resolution
Verify that the Live Assist script-tag is located within the document body on your pages (within the <body></body> tags) and not within the document head (within the <head></head> tags). Having moved the Live Assist script-tag retest IE11
To check the tags on your page see: Managing the Live Assist Tag.
