Hi,
You’re missing the script tag that holds the configuration for the realtime collaboration feature. This script tag is supposed to be inserted into the HTML page by the UI extension published by the XWiki.Realtime.Configuration wiki page. It looks like that UI extension is not executed, most probably because it wasn’t registered at wiki level. Did you check the history of the XWiki.Realtime.Configuration wiki page? Compare its latest revision with the revision coming from the “Realtime UI” extension. Are there any differences? If there are no differences, can you try to:
- edit this page in object mode with a user having wiki administration right
- expand the first “XWiki.UIExtensionClass” object
- type some text followed by an empty line at the start of the “Executed Content” field
- save
- open another page in view mode
- do you see the typed text in the top left corner, below the logo?
BTW, you didn’t mention what version of XWiki you are using.
Hope this helps,
Marius
