環境
- Confluence 6+
Diagnostic Steps
Check if enabling Collaborative editing through REST cause the same error by running this on a terminal:
curl -X POST --user admin_user:password --header "X-Atlassian-Token: no-check" https://your.confluence.url/rest/synchrony-interop/disable
Make sure to replace the admin_user:password with your admin credentials, and the Confluence base URL
- Check that there is no Synchrony process running
原因
Confluence tries to kill the Synchrony process, but Synchrony is not currently running or it is unable to stop the process. The error likely comes from a corrupt cache/file.
ソリューション
- From the Manage Add-ons page, disable and re-enable the Synchrony Interop plugin
- Confluence をシャットダウンします。
- Clear the plugin cache
Remove the /confluence_install/temp/synchrony.pid file
- Confluence を再起動します。
- Restart Synchrony / Collaborative editing
