Hi Shivvikram,
The node that the error is being thrown for is missing an internal property "jcr:predecessors" which is used for node versioning.
If this is preventing you from activating a page then the node missing the property is the jcr:content subnode of the page. To fix the issue, do the following:
- Log in to /crxde web app as admin user
- Browse to the page node /content/...
- Right click the jcr:content node under that
- Select "Mixins" from the context menu
- Remove the mix:versionable mixin type
- Save
- This will remove all versions for that page. The next time you activate the page it will work and the page will be given a new version history under /jcr:system/jcr:versionStorage/...
Thanks,
Andrew Khoury
