Collaborative Editing, also known as Concurrent Editing, allows multiple users to be editing the same content at the same time. Atlassian introduced this feature in Confluence 6.0. Collaborative Editing functions in Theme Press only under the following conditions: - When there is ONLY ONE content block on the page (and there has never BEEN more than one block*)
- When editing in "Edit Entire Page" mode**
* If a second block is added to the page, and subsequently removed, Collaborative Editing will not function.
** This mode is intended only for debugging and administrative actions (such as copying an entire page to another Confluence instance using two browsers), and can produce unexpected resultsAdd definition/concept description here. |
